Main functions of the system 1
The MAGNETOM Harmony (1T) and Symphony/Sonata (1.5T) comprise the following functions:
• Generation of the basic magnetic field
• Generation of the gradient field
• Generation and measurement of the high frequency field
• System control including host HW
• Patient positioning and monitoring
• System power supply
• Software
System components 1
Magnet system
The magnet system generates the basic magnetic field. The components required for the MAGNETOM Harmony (1T) and Symphony/Sonata (1.5T) are described below. The electrical and mechanical shim are integrated into the gradient coil. The magnet comprises the superconducting magnet including the system for cooling (interface for helium fill/refill, cold head), energizing (current probe) and monitoring the magnet during operation. In addition, it includes the cabling up to the point where the external lines are connected.
Whole body gradient system (GPA; Gradient coil)
In addition to the basic magnetic field, the whole body gradient system generates linear dynamic magnetic field gradients into the three room orientations. The whole body gradient system includes the gradient amplifier and the gradient coil.
RF system
The RF system generates the RF fields and transmits them to the patient (transmit function). It also receives the MR signals emitted by the patient and provides them in digital format for image recon-struction (receive system).
RF Coils
The system includes a whole body coil for emitting RF to the patient and for receiving MR signals from the patient. The tune box which adjusts the resonator to the performance amplifier as a function of fre-quency and load as well as the connection cables to these units are part of the body coil. The support tube of the body coil also functions as the inner cover of the magnet tunnel.
RF local coils improve image quality when examining specific body regions.
System electronics (GPA/CCA)
The system electronics cabinet includes power supply distribution, RFPA, GPA, RF-electronics and CCS.

Imager PC
The imager PC is responsible for the "image calculation" and is usually located in the equipment room.
RF-filter plate
The RF filter plate is the interface from the electronic cabinet into the RF room. All el. signals must be filtered to prevent interferences.
Alarm box
The alarm box is for switching on/off the MR system. It also contains the ERDU (Magnet-Stop) button.
Patient handling 1
Prior to the MR examination the patient is positioned on the table using the positioning accessories for additional comfort. During the examination, the patient is monitored accordingly, e.g. via video camera. The system handling function covers all requirements and includes the patient table, lighting, ventilation, and patient monitoring.
Since the patient is usually alone in the examination room during the measurements, patient and physician communicate via the intercom. The intercom consists of the configurations necessary in the examination room and the operating console as well as the cabling.
Whenever required, the patient is monitored during the examination via a video camera. The set up consists of the camera, the monitor as well as the cabling.

Regulatory affairs 1
Pressure Equipment Directive 1
The magnet qualifies as pressure equipment. When starting up and during the operating of pressure equipment, national regulations have to be observed.
In Europe, the Pressure Equipment Directive (97/23/EU) regulates the introduction to market of pressure equipment.
In Germany, the Pressure Equipment Directive as well as the "Betriebsicherheitsverordnung" (BetrSichV)(Industrial Safety Regulations) apply to system start-up and operation. The BetrSichV stipulates that prior to start-up the user or others must perform a final acceptance test consisting of inspection of documentation, safety equipment, and installation. Periodic inspections of the cryostat are not required. However, periodic internal tests and periodic strength tests are mandatory, if the equipment is taken out of operation for maintenance or repair work.
Druckgeräteverordnung 1
Der Magnet ist ein Druckgerät. Für die Inbetriebnahme und den Betrieb von Druckgeräten sind die nationalen Vorschriften zu beachten.
In Europa regelt die Druckgeräterichtlinie (97/23/EG) [Pressure Equipment Directive] die Inverkehrbringung des Druckgerätes.
In Deutschland gilt die Druckgeräteverordnung sowie die für die Inbetriebnahme und den Betrieb der Anlage relevante Betriebssicherheitsverordnung (BetrSichV). Die BetrSichV schreibt dem Betreiber u.a. eine Abnahmeprüfung vor Inbetriebnahme vor, die aus einer Ordnungsprüfung, Prüfung der Sicherheitsausrüstung und Prüfung der Aufstellung besteht. Wiederkehrende Prüfungen des Kryostaten sind nicht vorgeschrieben. Bei Druckgeräten müssen jedoch wiederkehrende innere Prüfungen und wiederkehrende Festigkeitsprüfungen durchgeführt werden, wenn sie zu Instandsetzungsarbeiten außer Betrieb genommen werden.
Local national laws, codes, regulations and procedures must be maintained.NOTE

Room planning 2General 2
When planning the MR-suite, the following influences the suitability of the site:
• Interference generated by the magnet
• Interference affecting the magnet
• Installation quality
• Noise emission
• Load capacity
• Minimum door height
• Minimum room height
• Cable routing
Information for using Digital and/or Laser cameras 2
The digital camera for syngo MR must be equipped with a DICOM interface.
Informations regarding Siemens Medical Systems released cameras for MR can be found under the following URL: http://cs.med.siemens.de/For Service/Product Information/Cameras/MR
Separate the cables from each other. The gradient cables must be separated from the signal and RF cables 300mm.
DO NOT COMBINE ALL CABLES TOGETHER.
If necessary instal additional cable trays.
Older digital camera models without DICOM interface will not work with syngo MR!
A special interface has to be installed between the Host PC and the digital camera.
Consult the installation manual of the laser/digital camera manufactorer for details regarding the fringe field sensitivity!

Effects of the magnetic field on peripheral devices 2
The fringe field may affect the functions of devices operated in the vicinity of the magnet. To prevent interference, the magnetic flux density at the location of these devices may not exceed certain values. The flux density acceptable for these devices depends on a number of different parameters. All perti-nent information is available through the manufacturer.

Site requirements for the magnet 2
The final location selected for the magnet has to ensure that the stability and homogeneity of the magnetic field are not adversely affected by extraneous fields. In addition, the magnetic fringe field should not impair the safety of personnel or the functions of other devices in the vicinity of the magnet.
Minimum distances between magnets (Siemens only) 2
The following minimum distances between magnets are valid if:
• Both magnets are on field
• No magnet is ramping during the other runs applications
• If one magnet is switched off the other magnet has to be re-shimmed
• Get in contact with the VR P / CS department if you have non Siemens products or older systems or if you have to plan e.g. two systems with the same operating frequency.
It is not possible to install electronics components (ECA/GPA/RCA/Optional RF-cabinet) of systems with the same operating frequency side by side!
Refer to: "Co-Siting" on page 2 - 15
The CCA cabinets have to be sepatated by 6m. The magnetic field of one system has to be ramped to the upper frequency limit of tolerance the other magnet to the lower frequency limit of tolerance!
Shim is only optimized with both magnets ramped up during the shimming procedure.

Source of interference 2
Effects on the magnetic field are divided into:- static interferences caused by e.g. ferromagnetic objects, especially those located underneath the
magnet- dynamic interferences caused by e.g. moving ferromagnetic objects or low-frequency magnetic
fields
In critical cases, either Siemens or a third party authorized by Siemens checks the suitability of the site. The tests are designed to detect electro-magnetic and mechanical sources of interference.
Siemens is not responsible for inspecting structural prerequisites, for example, the load capacity of floors or the heating and air conditioning system of the site. Similarly, Siemens is not responsible for executing or monitoring preliminary on-site installation steps. For these reasons, Siemens will not be held liable for the customer’s failure to maintain specific operating conditions.
Static effects can be compensated for by shimming.
Dynamic effects are compensated for by maintaining the maximum values indicated.
A magnetic shielding is required e.g. if minimum distances to static / moving iron masses or AC/DC cables cannot be kept.

One other scenario could be: A customer does have already a 1.5T system under operation and is getting a second 1.5T system in the close vicinity of the first one. In this case the new system must fulfill all requirements specified in this section "Co-siting prerequisites" on page 2 - 16. The already installed system should be modified in points where it is possible.
Magnet distances between magnets (Siemens used magnets only) 2
see also: "Minimum distances between magnets (Siemens only)" on page 2 - 4
It is not possible to install electronics components (ECA/GPA/RCA/Optional RF-cabinet) of systems with the same operating frequency side by side! Additional prerequisites are mandatory! ("Co-siting prerequisites" on page 2 - 16)
The CCA cabinets have to be sepatated by 6m (center to center Fig. 2; Fig. 3). The magnetic field of one system has to be ramped according to the ramp procedure to the upper frequency limit of tolerance the other magnet to the lower frequency limit of tolerance!
Shim is only optimized with both magnets ramped up during the shimming procedure.

Co-siting prerequisites 2
If two systems with the same operating frequency have to be planned (or one is already installed) take the following into account:
• The attenuation of the RF-cabin must be 100dB at the required operating frequency.
• For additional/optional waveguides the following calculation applies:
Lmin= length; di = inner diameter (di = < 250mm)
• The two RF rooms must not be electrical connected at all.
• The openings of the RF-rooms (e.g. door, window, waveguide) have to be turn away from each other. Having the mentioned openings (e.g. door, window, waveguide) facing each other must be avoided.
• The CCA cabinets must be installed in a min. distance of 6.0m ("CCA distance" on page 2 - 18) from each other.
• The cable ducts (CCA side) of the two systems have to be installed separated by 6m.
• The short cable set (1.5m) is not permitted to use with to systems in Co-Siting even if the CCA cabinet is installed directly underneath the RF filter plate.
• There must be a separate on-site power distribution panel as far away from each other installed for each system.
• The RF filter plates have to be positioned as far as possible away from each other.
• The connection of the RF filters (gradient and power) has to be performed as requested in the installation manual (e.g torque).
• According to the ramp procedure one of the MR systems has to be ramped to the upper frequency limit of e.g. 63.7 MHz (1.5T), the other MR system has to be ramped to app. 100 kHz lower than the first one see Fig. 1.
The following prerequisites for Co-Siting are mandatory for both of the two MR systems.

Field decay 2
The magnet marked "magnet 2" in the example in Fig. 1 has to be re-ramped first because due to the normal magnetic field decay the lower operating frequency tolerance limit will be reached earlier.
Fig. 1 decay
The special ramping procedure could require a different re-ramping time interval (to the operating frequency after the normal field decay) of the two systems!

The syngo MR software supports the application fMRI (functional imaging). Due to the magnet bore design the optical stimulation signals can only be fed to the patient from the rear. This fact has to be considered during planning when the customer will use fMRI. Additional space is required for the stimulation equipment at the rear (service end) side of the magnet (e.g. video projector, panel etc.).
Consult users manufacturer manual of the stimulation equipment for details regarding installa-tion, required space and distance to the magnet (fringe field).
Fig. 21 Recommended room configurations
If the patient cannot be observed (visually) through an RF window because of restrictions in the room layout, the patient video option must be included in the room planning.

Room planning 2 - 37
Minimum technical room sizes 2
Minimum distances
Room planning for MR-systems must be based on the minimum distances specified for safety and installation-related reasons. In the RF-room, the underflooring together with the floor cannot exceed the tolerance values specified.
To service the Magnet (e.g. cold head, current probe, etc.) the minimum finished room height must be guaranteed.
Minimum technical room height
The minimum finished room height measures from the finished floor to finished (suspended) ceiling.
Recommendation:
For future upgrades, e.g. "Symphony a Tim system" upgrade, it is required to plan for a finished RF room length of 6100mm!
The distance from the magnet iso center to the rear finished wall should be 2390mm.
(From the cover to the rear wall app. 1500mm)
The minimum technical room height has to be achieved for technical reasons but the dimensions should be enlarged.
The delivered set of Sylomer/Sylodamp pads for sound reduction is 50mm in height!
Take this into account while planning the min. room height!
The min. technical finished room height for removal of cold head, HDCL and syphon is 2350mm.

Temporary cold head compressor operation 3
For a temporary operation (e.g. if the primary chilled water is not present) of the cold head compressor proceed as follows:
• CLOSE the primary water "IN" valves for all available cooler see Fig. 14.
• CLOSE the primary water "OUT" valves for all available cooler see Fig. 14.
• CLOSE the valve for the water-cooled CCS see Fig. 14.
This procedure is only for a temporary operation of the cold head compressor with a low on site water flow (app. 10-15 l/min; max. 6 bar).
Fig. 13 top view 1

NOTE
The valves are located at the top of the RCA cabinet.
• Close the valves.
The valves are closed if the groove is in the vertical position
• Close the valves for the water-cooled CCS.

Option: Split floor operation kit for the RCA cabinet 3
Application:
The split floor option is fitted to prevent back flushing and spillage from header tank within the RCA unit. This can occur if the magnet is installed e.g. one floor above the RCA unit. The modification involves fitting a solenoid operated shut-off valve in the cooling return pipe from the gradient coil. The mechanical check valve is fitted into the cooling line feed to the gradient coil.
If the RCA cabinet is installed one floor above/below of the system components (CCA; Magnet) a option kit "split floor operation" with the part number: 71 20 954 is available to prevent a return flow of the secondary water into the water tank. This is only valid for SCHROFF RCA cabinets!
It might be necessary due to local circumstances to isolate the floor in the area where the RCA cabinet is positioned from the rest of the floor because of noise/vibration induction.

SC-10/SC-10L Shield Cooler System
Function
The SC-10 or SC-10L Shield Cooler is a two-stage refrigeration system that conductive cools the warm (77 K) and cold (20 K) radiation shields of the MRI Cryostat, maintaining the shields at cryogenic tem-peratures and reducing the loss of liquid helium.
The SC-10 Shield Cooler mates with the cryostat interface flange and shields provided by the magnet manufacturer.
The system consists of a helium compressor (either HC-10 or HC-10L), interconnecting gas lines, cables and the shield cooler. The helium compressor uses high purity helium gas for its refrigerant. There is no co-mixing of the helium refrigerant with the helium in the cryostat. The equipment is designed for continuous operation. Electricity and cooling water for the compressor are the only required utilities.
Pressures are stated as gauge, not absolute. Pressure units are bar and pounds per square inch (psig). For reference:
1 bar = 14.5 psig
1 MPa = 10 bar

Grounding 4
Siemens Medical Solutions products are sophisticated electronic systems that require attention to grounding to ensure optimal equipment performance and reliability.
Equipment grounds to the Siemens equipment are specified to be "isolated" type as permitted in NEC 250-96(b) for the reduction of electrical noise.
In order to maintain the integrity of the RF-shielded examination room, the ground must originate at the Siemens electronics cabinet ground bus (CCA cabinet), and should be connected at both ends under Siemens supervision.
Non-current carrying conductive surfaces shall be grounded by a #6 a.w.g. insulated green copper con-ductor installed in the metal raceway that contains the branch-circuit conductors supplying the equip-ment.
A neutral conductor if present is not used for the line voltage connection to the Siemens equipment. if the neutral conductor is provided it should not be electrically connected at any point in the power distribution to the siemens equipment unless specifically required. Unintentional neutral to ground bonds may violate local and national electrical codes as well as create grounding problems.
The grounding of the system, esp. the provided facility ground should be prepared obeying local regulations.
The internal grounding of the MR system must be setup with minimum ground loops in order to prevent noise currents and general disturbances flowing through the grounding path.
Grounding points 4
To achieve such a grounding three major grounding points should be used:
1. The provided facility ground in the distribution panel.
2. The main grounding point at the CCA cabinet (should be directly connected to (1)).
3. The RF-room common grounding point at the RF filter panel (should be directly connected to (1)).
4. An optional UPS System should be connected as well to (1).
To check for possible ground loops the ground resistance between the RF cabin (3) and the facility ground (1) should be checked prior switching on the system. The minimum resistance between (1) and (3) without connected ground wire should be at least 100 Ohm. After having measured that all ground wires should be connected and then the maximum resistance between any two points on the ground system should not exceed 200 mOhm.
Additional electrical equipment installed inside the RF cabin should use RF filters mounted on the filter panel. These additional filters should be grounded as well to the RF cabin common ground.
Any modifications or non-MR equipment grounds added to the MR ground system must be approved by Siemens representative to guarantee safety and performance of the system.

Power outlets inside the Examination room 4
Hazardous conditions are created by the magnetic field when connecting devices made from magnetizable material to the receptacles installed in the examination room.
In addition, the functionality of electrical devices, e.g. servo ventilators, may be affected by the magnetic field if the devices are not suitable for this type of operation.
The user is responsible for the installation an use of receptacles in the examination room as well as damages ensuing from said use.
In addition, the on-site electrical system has to conform to Applicationgroup 2 (VDE 0107) when life supporting systems are used in the examination room.
Power outlets inside the examination room must be connected through extra RF-filters and an insulation transformer if DIN VDE 0107 Applicationgroup 2 is required.

Room lighting 4
Intensity of illumination 4
The most important factors with respect to good lighting are the brightness level and light density which should result in reflection-free presentation and uniformity. Those parameters must be adjustable.
The room lighting fixtures should be divided into groups so that they can be adjusted to daylight conditions.
In reference to DIN 6868-57 the illumination in rooms which are equipped with e.g. monitors for diagnoses has to fulfill the following requirements:
- adjustable- non-dazzling- reproducible adjustment of the illumination density- no reflections from windows, lamps, display cabinets in the normal operation position of the e.g.
monitor.
Image screen workstations 4
The special requirements to be met by the human eye when working with image screen workstations are, for example, rapid image or text displays. An expert in room lighting should be consulted when determining the physical location of the MR monitors and the seating arrangement for the operator. Of special importance is the location of windows (daylight) and illumination with respect to the screen.
Planning 4
Reflections from light sources or daylight (windows) lead to completely false contrast and brightness settings on the MR monitor. Since the images and texts displayed on the screen are the basis for photographic documentation, the quality of images from this source will be negatively influenced. Equally important for optimal image quality on the MR monitor and thus for the most fatigue-free working conditions are such factors as reflection and glare, light density, and adequate illumination strength.
Reflections, glare 4
Glare considerably impairs the work performed at the screen. Direct glare due to lamps or illumination as well as various kinds of reflected glare should be prevented. Appropriate planning is therefore highly important.
The planning of the illumination and position of e.g. monitors should be done in reference to DIN 6868-57.

DC voltage 4
The magnetic field adversely affects the operating life of light bulbs located in the immediate vicinity of the magnet. The filament in the light bulb oscillates with the frequency of the power supply. It is therefore recommended to connect light fixtures in the vicinity of the magnet to a DC voltage supply. If room lighting is supplied with DC voltage, correct polarity of the sockets should be ensured during their installation.
Residual DC ripple should be ≤ 5%.
AC voltage 4
Only lamps without phase angle control should be used.
Fluorescent lighting must not be installed inside the examination room.NOTE

Protective Conductor Test 4
Use the protective conductor meter and measure the ohmic resistance between the protective conductor connection on top of the CCA cabinet and an uncoated metallic part of the:
• RCA
• CCA
• Imager computer
• MRC Host computer
• MRC console components
• RF-room
• RF Filter plate
• Magnet
• Patient table
• Monitor
• Options (if available)
Before performing the protective conductor test, read the operators manual of your measuring device!
For some measuring devices the resistance of the measuring leads have to be subtracted from the measuring result!
The entire grounding cabling must be installed, before this test can be performed.
The protective conductor test has also to be performed from the on-site power distribution panel to the connection (mains box) of the CCA cabinet. This is to ensure the presence of the ground connection at the connection terminal of the CCA cabinet.
Should the resistance exceed in one instance 200mΩ, test the protective conductor in question for satisfactory galvanic connection.
If this is not successful for devices with inlet-connectors (for non-heating appliances), an additional 16mm2 protective conductor should be connected to the respective housing. Do not disconnect the protective conductor in the line voltage cable.

On-site water supply 5General 5
• In Germany, DIN 1988 "Technical guideline for tap water installations" should be part of the planning phase.
• Local regulations will apply in all other countries.
• If the country in question has not established specific regulations, DIN 1988 should be used.
• Relief valves have to be installed in the water supply pipes whenever required by local ordinance.
An on-site water supply is required for operating the RCA. The primary chilled water supplies three components:
• The water chiller for the gradient coil, gradient cabinet, and RFPA amplifier.
• The helium compressor for operating the cold head.
• The CCS cabinet (optional water-cooled) for the cabinets requires water only when the system is switched on.
If you are using tab water you have to take in cocideration the following:
In case of a waterleak in the primary circuit water will flood the site. There is no automatic to stop the waterflow!
The same stands with the use oof the emergency cooling connection at the water transfer panel (if used)!
The helium compressor requires chilled water 24 hours a day.

It is absolutely necessary to achieve the require on site primary water specification. If the water quality is not as good as required damages to water-cooled components (e.g. cold head compressor) will occur.
The primary water circuit has to be flushed and the primary water quality has to meet our specifications (see "General primary water specification" on page 5 - 4) before the primary water circuit will be connected to our RCA cabinet (water interface).
In UPS mode, the switch on current of the water chiller must be limited to 2 ln.

General requirements 5
For the on-site water pipe installation only the following materials (for the water pipes) have to be used to guarantee a proper operation of the primary water circuit:
- copper- plastic medium pipes- stainless steel- high-grade steel- non-ferrous metal
Do not use:- standard steel pipes- zinc-plated steel- carbon steel
Do not use any of the below mentioned materials. Those materials will cause damages to the cold head helium compressor.
The specifications of the primary cooling water are related to the primary cooling water input at the RCA cabinet.
Pressure and temperature losses because of the distance and/or hoses between chiller and RCA cabinet are not included!
If the on-site cooling water does not meet our specifications, a separate water chiller for the primary cooling water has to be installed!
For a temporary operation of the cold head compressor (e.g. if no chilled primary water is available) consult the information at: "Temporary cold head compressor operation" on page 3 - 13

Air conditioning 6General 6
The capacity of the air conditioning system is based on the:
• heat dissipation from the system
• heat dissipation from the lights of the room
• heat generated by adjacent rooms or sun light
The air conditioning system selected should be designed to permit future expansion. In addition, the system should be equipped with sensors which would automatically switch off the air conditioning if an error occurs. The temperature and humidity values should be recorded by a thermo-hydrograph to ensure that the data required is available for troubleshooting.
The MR system is cooled most effectively when the system components are installed at the prescribed distances from the walls or ceiling.
If the input draws upon air from outside the building, we recommend installing an on-site filter of EU filter class 4 (DIN 24185/part 2) to remove dust particles > 10 µm.
Air currents 6
• maximum room temperature deviations should be less than 3 oC
• air current speed in locations used by personnel should be less than 0.2 m/second
The air conditioning unit must be carried out according to local/country/hospi-tal specific regulations/codes,
e.g. DIN 1946 (Germany).
A minimum fresh air exchange rate, related to the examination room volume of six (6) times per hour is recommended.
Higher fresh air exchange rates might be required due to local regulations or the system usage.
It is recommended that you install fresh air systems (100% fresh air intake)

If you order a system cable set with more than 11.5m total cable length (inside the RF-room plus outside the RF-room) you have to order the required extension for the pressurized hoses separately! If you do not order the exten-sions if needed you will loose liquid helium due to the boil off while the refrig-eration system is not running!

The cable set length identifies the "free cable length", this means from connection point to connection point! The cable length is not the distance between the components! You have to conciderate the cable feeding!
Again, one important information is:
The gradient cables inside the RF-cabin are 2m shorter then the other system cables: This means for example: If you have ordered cable set Nr. 1 (1.5/7m) the configuration could be as follows: Outside the RF-cabine: The electronics cabinet is positioned underneath the RF-filter plate attached to the RF-cabine wall.
Inside the RF-cabine: The gradient cables are 5m (the rest of the cables is 7m). The gradient cables have to go from the filter plate 1.5m up into the ceiling and at the magnet side 1.5m down; this means the distance of the filter plate to the magnet is app. 2m!
Separate the cables from each other. The gradient cables must be separated from the signal and RF cables 300mm.
DO NOT COMBINE ALL CABLES TOGETHER
In cases in which the standard cable sets (Harmony/Symphony/Sonata) can not be used (even after changing plans and shifting magnet and/or cabinets) we have the following solution:
A 15m/5m (15m inside the RF-cabin; 5m outside the RF-cabine) can be ordered at the logistics department in Erlangen/Germany.
The local PM will than get a paper to sign. (To make sure he knows that future options might not be able to be installed).
The cost of this cable set is app. additional 20.000 EURO€€€!

Explanation of the diagram:
It is necessary to have a router that can be left with the customer at no extra charge during the war-ranty period and beyond with a service agreement. The router remains the property of Siemens AG.
Router shall be installed in a central location (e.g. hospital computer room to avoid physical access to the router for security reasons)
Router can be connected to either the ISDN or analog connection.
Remote diagnostics and "Pro-active Event Management" require remote LAN access to our systems. A router is required for this which we provide to our customers at no charge during the warranty period and beyond that period if a service contract is concluded.
The router remains the property of Siemens AG. The required telephone connection (preferably ISDN) and the power supply must be provided on site. Even if several Siemens systems are connected to the same data net, only a single central router is required.
Of course, we observe the confidentiality of patient data in the framework of remote diagnostics and have provided security against access to it. Further information on the topic of data security can be found in the system-specific publications.
Network 7
The image system is equipped with a network card for Fast Ethernet (100 BaseT).
For detailed information about SIEMENS Remote Services (SRS), see PG TD00-000.891.01... (http://cs.med.siemens.de/For Service/Product_Information/PG/general)

Cable routing 7
The total cable length consists of the cable length required between the components.
The free cable length is the length between the exit points for the cables at the components.
Bending radius for cables 7
Observe the following minimum bending radius RB for the cables listed below:
- Gradient cable RB ≥ 135 mm (only with set of extended cables)- Transmitter cable RB ≥ 120 mm, when bent once- Transmitter cable RB ≥ 360 mm, when bent several times- Fiber optic cable RB ≥ 150 mm- Fiber optic cable for the patient supervision RB ≥ 45mm.
Door switches at the RF-room 7
The proper routing of the cables is absolutely important to achieve good image quality!
When planning the final location of the system components, do not exceed the maximum distance which is determined by the cable length. Take in consideration the required additional length for routing the cables e.g. through a cable tray at the ceiling.
Adjust the openings (wall, ceiling) to the size of the cable connectors
All doors of the RF-room must be equipped with a door switch.
(In the case of several doors, the switches must be connected in series.)

RF-Room 8Prerequisites for establishing the RF shielding 8
• RF-shielding is required in the examination room, because - all international and/or national RF-guidelines for the prevention of RF-interferences caused by
MR system operation have to be observed- interference-free operation of the MR system despite RF-interference in the operating
frequency range of the installation has to be ensured. Route all electrical lines in the RF-room via RF filters.
• Equip doors leading to the RF-room with a limit switch.
• To prevent extraneous electrical fields in the examination room, the following should not be installed or used:- Telephone connections- Extensions for in-house intercom systems- Fluorescent lights- Energy saving light bulbs
Refer to "On-site electrical installation" on page 4 - 1
• The RF-integrity has to be tested and the filter plate must be installed after completion of the RF-room. Requirements regarding RF-shielding.
• The shell of the examination and magnet room has been completed
• The concrete has been covered with a vapor barrier for MR-suites located in the basement
• All openings have been made (door frames, view window, air intake and exhaust, etc.)
• If required, magnetic room shielding has been installed and prepared for attaching the RF-shielding
By using a suitable design as well as maintenance plan, the manufacturer of the cabin has to ensure that the following operate without fail: the door lock-ing, especially the door handle and locking mechanism so as to secure contin-uous access to the patient in the examination room for emergency care and evacuation.
For the Quench tube installation refer to the following chapter:
"Quench Tube" on page 9 - 1.
The floor in the vicinity of the magnet (2.2m x 4.5m) must be leveled within maximum +/- 2.0mm

Door opening direction / Pressure equalisation opening 8
If your RF-room door opens to the inside, your RF-room manufacturer may be able to provide you with subsequent improvements. For new systems, the following are considered standard safety measures. We recommend to upgrade older systems to these standards.
The following alternatives are available:
- The door is reconfigured so that it opens to the outside into the control room.
- The door is replaced with an RF-sealed sliding door. It should be ensured that the door closes in a way that allows it to move away from the frame in case of overpressure, that is, it facilitates opening the door.
- The stationary observation window is replaced by a window opening into the control room.
- Panels are installed in the RF-room or the door that can be unlocked and opened to the outside in case of emergency. These panels require an RF-sealed installation. After opening the panel, the outlet should measure at least 600 x 600 mm2 . When using rectangular panels, the shorter side should measure a minimum of 60m mm in length. To ensure unobstructed venting, this opening cannot be subdivided. This means that e.g. RF-sealed honeycomb grids are not permitted. Also, easy removal of the panel by a person has to be ensured. In addition, a minimum distance of 1 meter to the next wall needs to be observed. The panel should be installed as far as possible toward the top to allow escape of the low-density helium.
- Your RF-room manufacturer can provide you with additional RF-sealed room openings that lead directly to the outside. However, these openings are also conduits for noise generated outside the RF-room. Again, these openings should be installed toward the top as far as possible to allow escape of the low-density helium. To maintain unobstructed flow through a pipe, the diameter of a 10 m long line has to measure at least 0.7 m. It is not permitted to use honeycomb grids in this line.
For doors moved via auxiliary drives (e.g. electrical or pneumatic), manual operation has to be ensured as well. An outside window should be in the vicinity to allow venting exhausted gas to the outside. After completing the remodeling, the integrity of the RF-shielding has to be tested again. If included in the installation, the observation window may be pushed in. The window usually includes wiring for the RF-shielding that needs to be worked through as well. However, rescue personnel may be injured by the resulting glass splinters. Depending on the construction and the thickness of the window, the operator has to provide suitable tools for breaking the window.
The opening direction of the RF-door has to be to the outside of the RF-room. As an alternative other appropriate means have to be provided in a way that pressure built up during a quench, when the venting fails to work adequately, will not prevent the RF door of the examination room from being opened.
An opening in the RF room (see alternatives) of 600mm x 600mm must be installed if the RF door opens to the inside of the examination room! This is mandatory!
The opening of 600mm x 600mm is recommended even if the door opens to the outside.

8 - 4 RF-Room
The air conditioning system for the examination room has to be a separate system with a direct air vent connection to the outside of the building.
If required, the RF-room manufacturer has to perform a separate/additional RF attenuation measurement after the complete installation of the RF cabin (Magnet is positioned; RF filter plate is installed).
To operate the MR-system, the RF-room has to be grounded at the points specified in the installation instructions. All other ground connections are unacceptable.
The RF attenuation in the RF-room must be min. 90dB in the 15-128 MHz frequency range. The measured value (after installation of the RF-room on-site) must be stated in the handing over protocol of the RF-room manufacturer. A copy of this protocol has to be inserted into the system owners manual.
All components of the RF-room and the interior fittings/accessories of the examination room have to be made from non-magnetizable material. Follow manufacturers specifications and instructions.

Galvanic separation 8
Galvanic separation has to be installed to avoid electrical noise being picked up by loops between the magnet, the Quench tube, the RF room and the building.
It is necessary to have one galvanic separation of the quench tube inside and one outside of the RF room.
The sketch below (Fig. 3) shows the installation parts to be used for the galvanic separation.

All electrically non-conductive supply lines for- oxygen, anesthetics or- fiber optic cables, etc.
routed from the outside into the RF-room must be fed through electrically conductive pipes also known as RF-sealed wave guides. They must be either welded to the RF-shielding or attached to it with screws. The RF-sealed wave guide function is as hollow wave guide which is blocking certain frequencies.
Metal pipes (e.q. technical / medical gases, water...) must be grounded at the RF-wave guide. All international / national RF-regulations and ordinances must be followed. A proper and disturbance free operation of the MAGNETOM system must be guaranteed.

Information on medical gases 8
Only licensed firms (e.g., Dräger) are permitted to perform installations.
Up to now there were actually three ways of laying medical gas lines:
• Pipes were comprised solely of plastic tubing and were introduced into the RF-room through a 76mm feed-through. This is actually the simplest solution from a technical standpoint.
• Complete line voltage supply in copper tubing within the hospital. Copper tubing also installed inside the RF-room. The RF feed-through from the outside to the inside was established using the 76mm feed-through and synthetic tubing. In the area of the feed-throughs inside and outside of the RF room, inspection ports are required inside the suspended ceiling. Dräger performed the installation of the copper tubing and the transition with plastic tubing.
• Introducing the copper tubing directly into the RF-room via a RF-sealed copper tube. A type of mounting plate upon which the necessary number of copper tubes of the appropriate diameter are located. In the majority of cases, diameters of 8, 10, 12, and 14mm are required for the gases, while diameters of 20 or 25mm are required for suction. RF integrity can be calculated precisely using the diameter and length of the tubing.

Air conditioning 8
Honeycomb wave guides consist of a large number of small hollow wave guides. Depending on their dimensions, the honeycomb wave guides block certain frequencies. The honeycomb wave guides are used as RF-sealed feed-throughs for e.g. the air intake and exhaust ducts of the air conditioning unit. Refer to the data sheets of the manufacturer for additional details.

The RF-room is isolated from on-site ground, when the resistance between any of the points in the RF-room and the central protective conductor of the system is greater than or equal to 100 Ohms.
Measurement devices 8
Protective conductor meter.
Preferred method of measurement 8
• Construct the RF-room and measure the resistance between the RF-room and the central protective conductor of the system.
• Measure the resistance between the RF-room and the central protective conductor of the system each time an anchor has been set into the floor.
• After completion of the RF-room, the resistance between the RF-room and the central protective conductor of the system must exceed 100 Ohms.
• The RF-room cannot be connected to the on-site ground.
• Final measurements with the protective ground meter- Remove all protective conductor connections to the RF-room.- Measure the resistance between the RF-room and the on-site ground with the protective ground
meter.
The resistance must be >100 Ohms.

RF-room designs 8
RF-Room interior 8
The following informations are important for a faultless operation of the imaging system!
• Only non-magnetic materials are to be used and installed within the RF cabin.
• A suspended ceiling must be statically suspended, i.e., not suspended with movable clamps, springs, etc.
• Corrugated rods (e.g. for air conditioning systems) in suspended ceilings must be fastened securely (galvanic contact between the corrugated rods must be guaranteed, not just lying on top of one another; a wire jumper between the rods might be useful).
• Electrical wiring, e.g. for lights, must not be resting unsecured on the suspended ceiling.
The opening direction of the RF-door has to be to the outside of the RF-room. As an alternative other appropriate means have to be provided in a way that pressure built up during a quench, when the venting fails to work adequately, will not prevent the RF door of the examination room from being opened.
An opening in the RF room (see "Door opening direction / Pressure equalisa-tion opening" on page 8 - 3) of 600mm x 600mm must be installed if the RF door opens to the inside of the examination room! This is mandatory!
The opening of 600mm x 600mm is recommended even if the door opens to the outside.
By using a suitable design as well as maintenance plan, the manufacturer of the cabin has to ensure that the following operate without fail: the door lock-ing, especially the door handle and locking mechanism so as to secure contin-uous access to the patient in the examination room for emergency care and evacuation.
If you expect noise problems the RF-Room manufacturer you are using might be able to deliver noise reduction components with the RF-room(e.g. interior; RF-window; RF-door etc.).
Adhere to the manufacturers guidelines, specifications and/or installation manuals.
Be aware to add the weight of the RF-Room and / or external iron shielding and / or noise reduction material into your static calculations!
Special devices like medical gases feed through or RF-filters for e.g. room lights could be possibly ordered from your RF-cabin supplier/manufacturer.

Modular RF-rooms 8
The shell of the examination room must have been completed prior to assembling and installing the RF-room. The wall openings for e.g. RF-room door, view window, air intake and exhaust ducts, etc.have been made.
The modular RF-room consists of individual sections (modules) made from non-magnetizable material.
• No special structural requirements are needed for the ceiling and the walls.
• If sections of the completed modular RF-room have to be disassembled for installation-related reasons, new contact springs have to be used when re-assembling the sections.
• The modules have to be disassembled in groups from the floor to the ceiling or up to the respective corner of the RF-room. The same applies to the ceiling panels.

a) the magnetic fringe field strength shall not exceed 0,5 mT and
b) electromagnetic interference level complies to IEC 60601-1-2: 1993; - shall give clear recommendations as to how this CONTROLLED ACCESS AREA shall be delimited, e.g. by markings on the floor, barriers and/or other means to allow the responsible staff to adequately control access to this area by unauthorized persons; and - shall state that the CONTROLLED ACCESS AREA should be labelled at all entries by appropriate warning signs, including an indication of the presence of magnetic fields and their attractive force or the torque on ferromagnetic materials.
When the MR EQUIPMENT is designed for installation in a room in which audio visual contact to the PATIENT is likely to be limited, the technical descriptions shall specify provisions in the design of the room and in the EQUIPMENT to enable audio and visual contact with the PATIENT during the MR EXAMINATION. The audio visual contact shall be sufficient not to hamper the possible need for MEDICAL SUPERVISION of the PATIENT.
When the installation of a CONTROLLED ACCESS AREA is required for the MR EQUIPMENT, the INSTRUCTIONS FOR USE
- shall state clearly, that it is the responsibility of the USER to follow local statutory requirements with respect to access to the CONTROLLED ACCESS AREA;
-shall specify, preferably accompanied by a sketch, the size and shape of the CONTROLLED ACCESS AREA;
- shall indicate the need to establish adequate rules for controlling access to the CONTROLLED ACCESS AREA in terms of the potential risk to PATIENTS and staff within the CONTROLLED ACCESS AREA from the attraction of objects containing iron or other magnetically active materials or from torque on such metallic materials and the potential risk to persons inadvertently entering the area who may be affected by the possible dysfunction of their medical implants such a pacemakers;
The project manager has to inform the customer to protect the controlled access area (0.5mT) with e.g. the delivered warning signs (or markings on the floor or an alternative adequate solution). All doors leading into the 0.5mT area must be identified/protected with a warning sign. The project manager provides the customer with the position of the 0.5mT line based on, e.g., a table from the planning guide that shows the distances or the customer site drawings that indicate the 0.5mT line. The warning sign “cardiac pacemaker” is, e.g., for identifying the 0.5mT line. The warning sign “strong magnetic field” is, e.g., for identifying the entrance doors into the examination room or the 0.5mT line

For all EQUIPMENT, ACCESSORIES or tools listed, a description should be given of special measures that are needed, if any, for its installation as well as special pre-cautions, if any, for their use
- shall state clearly that peripheral equipment, including PATIENT monitoring, life supporting devices and emergency care equipment, which are not specified or recommended for use in the CONTROLLED ACCESS AREA, may be disturbed by the radio frequency field or the magnetic fringe field of the MR EQUIPMENT and that this peripheral equipment may also disturb the proper function of the MR EQUIPMENT.
Used DIN norms 8
Shielding attenuation measurements are normally carried out in compliance with the following standards:
• EN 50147-1 (European standard)
• NSA 65-6 (American standard)
• MIL STD 285 (American standard)
• IEEE 299 (1997)
The various methods for measuring are established and described within the standard. It is, therefore, common for us to determine certification measurements with the respective customer as early as the quotation and planning phase.
For magnetic field strengths less than 0,5 mT no administrative controls are required.

Quench Tube 9General 9
In the event of a quench, the thermal energy dissipated causes an extremely rapid boil off of the liquid helium. The system must be capable of venting the large volume of gas generated at the approximate expansion ratio of 1:700 from liquid at 4.2 K to room temperature gas. The exhaust system is critical for the safe operation of the magnet, and the guidelines set out in this section must be followed. Since helium vented in a quench is an asphyxiant and an extremely cold gas, the quench tube must always end at a point where access by people is not possible. This is similar to venting dangerous gases in chimneys.
Planning and installation of quench tubes must be conducted by qualified personnel. Note that components used for other tubing, e.g., in air conditioning or room venting, are generally not suitable for quench tube construction.
It is the responsibility of the operator of the equipment to ensure that the quench tube pipe is maintained in an operable state.
Basis for design calculations 9
Calculating the pressure drop along the quench tube during a quench is complex due to the compress-ibility of gas and the heat inputs along the length of the tube, which affect the gas density.
The sizing procedure relies upon tabulated data, which are used in simple arithmetic calculations. The tables are based on empirical data derived from quench test pressure loss measurement. An example of the sizing process is contained in the following section: "Quench tube sizing example" on page 9 - 15.
The quench tube design has to comply with the requirements specified in this document. It is the responsibility of the Project Manager to accept the installation of the quench tube before the magnet is connected!
The quench tube outlet, as well as the quench tube, must be easily accessible for visual inspection!

9 - 2 Quench Tube
Quench tube components checklist 9
The following specific design rules apply to the components making up the quench tube:
1. The quench tube will comprise straight, hydraulically smooth tube sections, bends (up to 90°) and a diffuser if required (Fig. 8). The end of the tube must be terminated in a way to prevent ingress of rain, snow, and foreign objects (Fig. 1; Fig. 2). Flexible sections are used to connect to the magnet, and as expansion joints ("Principle layout of a quench tube example 1." on page 9 - 15). If a quench line is very short and straight, a flexible tube may be used for the whole of the quench line. Note however that due to the high pressure drop, the maximum permissible length of flexible tubes is very short as compared to straight tubes.
2. The quench tube must be made from a non-magnetic material. Only stainless steel grades AISI 304, 309, 316, and 321 [EN 1.4301, 1.4828, 1.4401, and 1.4878] may be used.
3. Due consideration must be given to thermal contraction (up to 3 mm/meter for stainless steel). Stainless steel bellows sections must be used to allow for adequate contraction. Bellows are to be fitted at a minimum of every 10 m. The movement of the bellows must be limited so that the pipe does not expand excessively under internal pressure.
The length of the bellows sections in total may not exceed 2% of the allowed maximum pipe length, in order that the pipe pressure drop does not increase excessively. The weight of the tube must be supported against the building. In order that the line suspension is not overstressed due to the thermal contraction, the suspension needs to be flexible enough to accommodate the movements. Also, the wall exit in general should not be fixed hard to the wall. The maximum internal pressure of the pipe in the design calculations is 0.1 bar. The maximum permissible pressure, however, needs to be 0.45 bar. The quench line has to be constructed in accordance with sound engineering practice.
4. There must be a flexible section at the quench valve in order to reduce noise transmission, ease the fitting of the quench tube, and so that the quench valve does not carry any load from the weight of the quench tube. The flexible section at the quench tube should be about 0,3m to 0,5m in length, the internal diameter must be at least 0.102 m (4"). It is to be made of stainless steel, and has to be able to withstand a maximum permissible pressure of 0.45 bar over atmosphere. The flexible section has to be installed nominally straight, i.e., to allow for minor misalignment. It must not be bent in a way to replace an elbow. The length of this section should be accounted for according to Tab. 2.
5. Joints may only be made by welding (by stainless steel qualified welders), or by bolted flanges. Rotary flanges are permitted to ease the installation process. Vee clamped flanges may not be used. Gaskets used to seal section joints are to be made of either UHMW-PE [Cestilene HD1000, Hostalen GC579, or Hostalen GUR812], PTFE [BS EN 13000-1:1998, BS EN 13000-2:1998], or fiber [ASTM F36, BS 7531, DIN 3754P]. No other materials are permitted.
Flexible tubes and bellows may only be made of stainless steel.
(For material grades see paragraph 2.)

Quench Tube 9 - 3
6. The end of the quench pipe must be protected from outside elements such as rain or snow. It will be fitted with a wire mesh. The mesh size is to be 10±1 mm [3/8"], with 1 mm round wires, to prevent ingress of foreign bodies [e.g., birds and rodents]. The area of the mesh must be at least 2.5 times the cross-section area of the quench tube (Fig. 2).
7. Where the quench tube exits through a flat roof, the outlet must be above a level where water could enter it in the event of the roof drains becoming blocked. Where the quench tube exits vertically, a rain shield must be fitted(Fig. 1). A deflector plate must be welded to the tube where it exits the roof to prevent helium from re-entering the building (Fig. 1). The deflector plate must be at least the same diameter as the rain guard. It must be located at least two pipe diameters above the roof, and two diameters below the bottom of the rain guard. In the case of a horizontal exit through a wall, the outlet must be turned down by not less than the pipe diameter to prevent rain ingress (Fig. 1). The exit must be situated where it cannot be blocked by drifting snow.
8. To avoid the risk of injury from cold burns and asphyxiation, access to the quench tube must be restricted by 3 m each side and below, and 6 m vertically above the exit; warning signs must be put up (Fig. 1). The exit must not be situated where, in case of a quench, helium gas might be drawn into an air inlet, or where gas might enter open windows. Note that helium is lighter than air, even when very cold. The cold gas must not be allowed to blow directly onto a window.
9. All bends must be smooth walled and have a centerline radius to internal pipe diameter ratio in the range 1.5 to 5.0. Where a one-piece bend is not readily available, a fabricated bend using straight sections is permissible (Fig. 6).
10. Mitred elbows (Fig. 7) may be used, but be aware of the much greater equivalent length (Tab. 3), which makes them very unfavorable.
11. Expansion from a small to a large tube diameter will be accomplished using a diffuser. Diffusers will conform to the geometric parameters shown in Fig. 8. Never reduce the diameter of a line in the downstream direction.
The area of the mesh must be at least 2.5 times the cross-section area of the quench tube.
Only the examples of pipe exits in this guide may be used.
Where windows are within the restricted access area, they must be sealed and permanently closed. Means of opening the windows must be removed.

12. The pipe is to be insulated along its full length. This is to avoid condensation of liquid air in case of a quench, as well as water condensation on the inside in humid weather conditions. A double-walled structure is allowed. Mineral fiber insulation (brands such as Rockwool Ductwrap or other) must not be less than 25 mm thick. The insulation must conform to local regulations for fibrous insulation materials. Within the RF room, the pipe is to be insulated with one layer of mineral fiber insulation 25 mm thick with vapor barrier, covered with one layer of 25 mm thick Class O Armaflex [Armacell]. Vapor barriers must not make electrical contact between the magnet pipework and the wave guide, in order to avoid RF disturbance to the imaging system. The outside may be covered with an aesthetic finish. Outdoor pipes must be covered if access cannot be excluded at the pipe or below (dripping liquid air in case of a quench). Outside insulation must be weatherproof [e.g., Armafinish FR paint, or Arma-Chek insulation].
13. The pipe must be marked along its length with a warning tape stating its function, e.g., "WARNING: Vent pipe for extremely cold helium gas - work only by authorized personnel."
14. In order to achieve galvanic separation between the imaging system, the RF room (cabin), and the building, two galvanic separations are required. The separation at the magnet has to be made at the magnet exhaust flange, using stainless steel bolts, insulating bushes and locking nuts. The same principle is to be used outside the cabin.
15. The quench tube design has to comply with the requirements specified in this document. It is the responsibility of the Project Manager to accept the installation of the quench tube before the magnet is connected.
16. Documentation:
For safety reasons, no other designs are permitted.
The design and construction of the quench pipe needs to be documented in drawings and calculations, and kept with the installation documents.

9 - 10 Quench Tube
Sizing procedure 9
The sizing procedure for the quench tube must follow the steps outlined below.
1. Define the length of the flexible tube to be used (typically 0.5 m). Calculate the share of the maximum permissible length used by the flexible tube (Tab. 2).
2. Determine the approximate length of tube required to reach from the flexible tube to the end of the quench tube, where it exits to atmosphere. In terms of the pressure loss along the tube during a quench, the apparent length of the tube is longer due to the extra frictional losses around the bends. As a first approximation, pick a diameter from Tab. 1, Tab. 2.
3. Layout line with bend elbows. Check bend radius to diameter ratio for all elbows (Fig. 6; Fig. 7)
4. The apparent length (LA) is calculated as LA = L1 + L2 +...+ Lm + E1 + E2 +...+ En, where L1..m are the straight lengths and E1..n are the effective bend loss lengths from table Tab. 3.
5. Check whether the resulting LA is within the limit allowed in Tab. 1, Tab. 2. If the line is longer than allowed, go to a larger diameter and repeat steps 2,3 and 4.
6. Determine the correct length for a diffuser, if required.
7. Determine the required size for the protective rain guard.
8. If there is a need to use more than one diameter for the line, calculate the percentages of the maximum permissible tube lengths for each diameter from table Tab. 1, Tab. 2. The sum of all percentages, including the flexible section at the magnet needs to remain below 100%.

Quench tube sizing example 9
It is determined that the quench tube will need to be about 12 metres in length. The tube includes two elbows. A 0.102m (4") flexible tube of the length Lf = 0.5m connects the quench tube to the outlet of the quench valve (Fig. 9).

9 - 16 Quench Tube
1. From Tab. 2 the permissible length of 0.102m (4") flexible tube is 1.92m. A 0.5m long tube accounts for 0.5m/1.92m = 26% of the total permissible length.
2. The required 12 metres of the quench tube should not exceed the remaining 74% of the total permissible length. Take 12m * 100% / 74% = 16.2 m. From Tab. 1 select a diameter for the tube that will contain the length required. In this case 0.52m (6") gives a maximum permissible length of 28 metres.
3. Check if bend radius to diameter ratio is larger than 1.5 (Fig. 6). A commercially available smooth walled elbow has an R/D ratio of 2. It can be used for bend 1. It is necessary to use a tighter elbow for bend 2. Since a one piece pipe is not available it is decided that a 5 segment fabricated pipe will be used where R/D = 1.5. The effective lengths are taken from Tab. 3.
4. Determine apparent length LA. LA = L1 + E1+ L2+E2+L3= = 2 + *1.73 + 3 + *3 +6= = 15.73 m (* : taken from Tab. 3)
5. The apparent length of 15.73m should take less than 74% of the permissible length. Take 15.73m * 100% / 74% = 21.26m. This is less than the maximum permissible length of 28m (Tab. 1) and the pipe size selected is acceptable.
6. A diffuser is required to connect the 0.102m outlet on the quench valve to the 0.152m ID pipe. From Fig. 8 the length of the diffuser is 0.128m min. The longer the diffuser the better so in this instance because space permits, a diffuser 1 metre long is used. It is acceptable to count the diffuser length to the straight length.

Cryogen supply 10General 10
For satisfactory operation of the MR system, liquid as well as gaseous helium is required.
Because of the physical characteristics and the price of liquid helium, the cryogen has to be handled according to the special instructions given in the subsequent pages.
As early as in the planning phase, the structural and logistic aspects of gas supply for the MR system have to be established.
The liquid helium is transported in containers especially designed for this purpose (dewars).
Structural requirements 10
Since the vessel dimensions for liquid and gaseous helium must meet certain specifications, the follow-ing issues have to be clarified with the supplier prior to delivery:
1. Access routes
2. Width of doors
3. Size of elevators
4. Height of rooms and hallways
5. Temporary and permanent storage area for gas cylinders
6. Load capacity and condition of transport routes
Every reputable supplier provides liquid helium dewars of non-magnetizable material. However, cylinders for gaseous helium are usually made from mag-netic material. These cylinders must remain outside the vicinity of the magnet when it is energized.
To move the Helium dewars into the MR-suite, evaluate the height and width of all access routes and doorways during the planning phase.

Transport methods for helium 10
Liquid helium is transported from the supplier to the magnet in dewars holding between 100 to 450 liters of liquid helium. The dewars are transported in special trucks equipped with an elevator platform. Special containers are available for air-freighting liquid helium.
Dimensions of the dewars 10
After the transport routes have been determined, the dewars and the refill equipment required have to be established.
The following items require clarification:
1. Dimension and fill capacity of dewars?
2. Pressurized or non-pressurized dewar?
3. Supplier provides a full set of refill equipment?
4. The syphon attaches to the magnet?
The following suppliers provide a full set of refill equipment:
- Linde AG- Messergriesheim GmbH- Air Products GmbH
Delivery of magnet 10
The magnet is shipped cold (standard case). 10
The magnet is shipped warm (exception). 10
The magnet is cooled on-site with- approx. 2000 l liquid nitrogen- approx. 3500 l liquid helium- approx. 10 He cylinders (200 bar / 50 l / 99.99% grade 4 purity)
The liquid cryogenic should be available on-site at the time planned for start-up of the magnet.
Magnets that are shipped cold leave the factory with a fill level of approx. 70%.
To keep helium boil-off to a minimum, the refrigerator (cold head) should be put in operation as soon as the magnet arrives at the site.
Special equipment is required for filling the magnet.
Technical support as well as equipment (pumps, leak tester, flange, etc.) are available from OMT.
To avoid start-up delays, clarify the logistics and technical details pertaining to deliveries of warm magnets in advance.

For planning purpose it is important to know the following: 11
When the In-room MRC is installed a transformer has to be installed inside the examination room at the filter plate. A special position with already prepared bolts on the filter plate is prepared.
If due to any reason (e.g. sound reduction; thick wall) the cutout in the wall/sound reduction construction for the filter plate is exactly the same dimensions as the outer dimension of the filter plate the transformer can not be mounted to the filter plate!
The transformer has to be mounted in this case in the close vicinity of the RF filter of the filter plate. The cable length is 700mm.

Notes 11
POWER CONDITIONING DEVICES NOT APPROVED BY Siemens Medical Solutions MAY NOT BE COMPATIBLE WITH THE MAGNETOM SYSTEM. SUCH DEVICES ARE INSTALLED AND APPLIED AT THE CUSTOMER'S RISK.
In countries where the power supply is not reliable, UPS systems are used to supply the required power to the MR system, and in special cases to the chiller, when there are power interruptions or power failures. When there is a power failure, the UPS backup allows the MR system to be shut down normally or supplies power to the MR system during the time required to transfer to an emergency power supply. This allows you to complete measurements that have already been started. The UPS offers the additional advantage of reducing system downtime due to hardware and software errors.
Special power requirements if the on-site power is provided through a UPS system 11
The following table gives values, which should be used to select a suitable UPS system under the condition, that the water chiller is not connected to the UPS. If the water chiller should be connected to the same UPS, the required values power/current (the maximum possible value, e.g. switch-on current) for the chiller should be added to the values given below. In this case the chiller must be equipped with soft start compressors.

The factor in this column is defined according experiments with specific UPS model series. The factor may vary according to manufacturer and model series, the minimum factor applied should be 1.20. If the UPS model series is not released by the factory (see list below) a qualification procedure is recommended.
During the switch on procedure high current pulse amplitudes are possible. During this pulse the UPS may switch into by-pass mode.
The switch-time between battery mode and by-pass mode should be less than 1 ms. The UPS should fulfill local regulations additional to the above listed requirements.

Information on transport 13Transport and storage specifications 13
Mechanical conditions 13
During transport, the components are subject to mechanical stress. The recommended reference values for various mechanical environmental parameters are specified in IEC 721-3-2 (Transport) and IEC 721-3-5 (Load in Road Vehicles).
However, these reference values significantly exceed the acceleration rates measured on loaded trucks with an air suspension system. According to experts who routinely perform vibration experiments in test labs, the guidelines of IEC 721 cannot be practically applied to components with mass ratios such as those found in MR systems.
With regard to impact loads, the maximum acceleration duration on the loaded trucks with an impact duration of 20ms is 1.4g on the tractor and 4.7g on the trailer. Our current specification for the magnet is 2g horizontally (x, y) and 5g vertically (z).

Transporting the magnet and the cabinets (GPA/CCA; RCA) 13
Transport route 13
• Prior to requesting the services of a licensed carrier, the project manager and the architect/construction engineer must determine the floor loading of the transport routes and the temporary storage areas.
• The architect/construction engineer must confirm in writing that the floor loading of the transport routes/storage areas selected will suffice for moving the magnet and the system components.
• It is the responsibility of the carrier to obtain information concerning the various transport routes before the actual transport.
Issuing the order 13
• The order for transport must be issued in writing to the licensed carrier selected and must contain the following data and documentation (in addition to such general information as a list of the components to be shipped):- Copies of the transport routes/storage areas selected- A copy of the certificate attesting to the weight capacity of the floor- Final destination of transport
(to give the carrier enough time to obtain information regarding methods of transport and transport routes)
- The weight and dimensions of the components to be transported
• Actual transport- The project manager is responsible for the availability of the transport equipment to be used- The carrier is responsible for the type of transportation and auxiliary tools used
All transport activities including delivery of the magnet and the system components into the MR-suite have to be performed by a licensed carrier only.

Mobile specific requirements 15Responsibilities of the Project Manager 15
The Siemens Project Manager is responsible for the mobile system installation process like he is for a static system installation. He should arrange with the trailer maunfacturer the delivery schedule of the system and the mobile kit (needed for the installation) to the trailer manufacturer. He has to arrange also the magnet, system installation and start-up. He is responsible for ensuring that the differences from a static system to the mobile system are implemented as described in the Planning Guide and in the Installation manual.
General 15
The MAGNETOM Harmony, Symphony and Sonata MR systems are originally developed for static use. However, all components are designed and tested also for being integrated as a mobile MR system.
in the Installation manual
The mobile system consists of a standard MAGNETOM Harmony, Symphony or Sonata system with minor adaptations and the trailer.
Because of the mobile system is based on a released ”static” system developed and tested according to Siemens Medical Solutions MR Quality System, only the mobile specific requirements are listed in this section of the Planning Guide. The static system has already incorporated the requirement of mobile use for the components. For the magnets the tests and mobile releases were done by Oxford Magnet Technology. Using the already prepared fixing points of the magnets in the mobile.
In Europe only HEGELE is allowed to install the the MR system into the trailer!
In the U.S.A. the trailer manufacturers install the the MR system into the trailer!
This complete document (Planning Guide) defines the requirement specification for the specific use as a mobile system.
The principal architecture of MAGNETOM Harmony, Symphony and Sonata with the respective components is given as technical constraints for the mobile system. All the valid specifications have to be taken into account for the mobile system also. The length of the cables can only be varied in the range given in the Planning Guide.

Data Analysis 15
• Data analysis shall be conducted using an appropriate data analysis system based on the technique detailed in the Analysis Algorithm shown in Fig. 9.
Demonstration of Compliance – Type Test 15
• The performance of vehicle suspension systems must be evaluated using the procedure detailed in section "Requirements" on page 15 - 11 of this document.
• Trailers not meeting this specification which are consequently commissioned and enter service will immediately invalidate OMT product warranty.
• For any subsequent modifications to the trailer type, a documented engineering change process must be implemented between the MRI system manufacturer and the trailer manufacturer, which ensures that a form, fit and function philosophy, is implemented. Within this process any engineering changes likely to affect the performance of the trailer against section "Requirements" on page 15 - 11 of this document shall require an additional type test.
• In respect of any claim against OMT product warranty, OMT reserves the right to review the build standard of any specific trailer operating with OMT product within the trailer, against the build standard of the type test trailer and associated results. Should build standard differences be noted, OMT reserves the right, prior to supporting any claim against OMT product warranty, to require the test outlined in section "Requirements" on page 15 - 11 of this document to be repeated for the specific trailer in question to ensure that the “In service” specification is being met.

On site preparations for the use of a Mobile MRI 15
General 15
The mobile unit does require specific site preparations, provided by the user at each desired location. The following information is necessary for the placement of the mobile system at a location. Included in this Planning Guide is structural and electrical information to assist the customer with design requirements. The informations herein are provided to suggest location of the mobile unit and are not for construction purposes.
Construction drawings are the responsibility of the customer and shall comply with all governing codes and regulations, as well as the trailer manufacturer's siting requirements.
Topographic specification 15
Access consideration 15
Access consideration must be given to the tractor, the patient lift, the stairs and the belly compartments, for patient entry, trailer service and helium dewar access to fill the magnet.
Service access 15
• An access way of at least 1 meter in width must be provided along the closed side of the trailer.
• An access way of at least 3,5 meters in width must be provided along the entrance side of the trailer.
• A clear paved space of at least 2 meters must be provided along the rear of the trailer.
• A clear paved space of at least 3 meters must be provided along the front of the trailer.
• A clear ceiling height of 5,2 meter is recommended for service access, if the trailer is to be placed inside a building or under an overhead walkway.
When parked, the MRI unit uses two front hydraulic jacks and two fixed height stands in the rear, for stabilizing purposes or four fixed height stands if a full size pad is available.
The axles must be leveled if the trailer is in its operating position.
If any kind of leveling material is used underneath the trailer supports, the same kind and thickness of this material has to be used underneath the wheels.

Controlled area 15
See also: "Controlled access area" on page 8 - 20
If a patient walkway is constructed from a building to the trailer it is recommended that it must be made out of non-ferrous material. The connection to the trailer wall to be made out of a soft material.
Due to the fact that the trailer is executed with magnetic shielding, the 0.5mT line remains within the width of the trailer. Therefore additional safety-provisions outside (sideways) the trailer are not necessary. Nevertheless heavy steel constructions may influence the optimal image quality.
Clearly readable signs and appropriate pictographs have to be posted on the trailer wall at the locations of largest fringe field stating the following (as for content): Warning: Strong Magnetic Field, pacemaker patients keep clear min. 50 cm (20 inches).
While in operation at a clinical site a chain (or other means preventing persons from accidentally coming closer than 50 cm to the “hot” areas) must be installed around the trailer. The truck operator (driver) must be instructed that he must not leave the trailer unattended on a public parking lot for an extended period of time (more than 10 min.).

Mobile specific requirements 15 - 37
Support pad 15
Recommended support pad size
For operational set-up an ordinary flat and horizontal solidly paved parking space is needed. For correct horizontal positioning of the unit the horizontal segment of the parking space (support pad) should be 10 x 3 meters. A total paved area of at least 6 x 20 meters is recommended for tractor access and patient handling.
Support pad strength
The support pad strength varies due to local codes and soil conditions. The pad should be able to carry the following weights:
Support pad levelness and flatness
Position Weight
King-Pin (front) 9 t
Bogey (rear) 19 t
total trailer weight app. 28 t
The support pad must be level and flat to insure proper operation of the mobile MRI unit.

15 - 38 Mobile specific requirements
On-site environmental requirements 15
Water requirements
The trailer has a humidification system which contains a water storage tank, located typically in the front side area (technical compartment). This tank must always contain water to ensure a specific humidity level. To fill the on board water tank a hose connection should be provided at the outside of the building in the close vicinity where the trailer will be parked.
Communication service
Provide communication access at the outside of the building in the close vicinity where the trailer will be parked. The trailer unit should be supplied with two double UTP connectors for communication.
Power requirements
The unit is standard executed with a diesel generator for the power supply of the water chiller, cryo-compressor, air-conditioning and ventilation during transport.
For operational use at the hospital site a 480 Volt / 125 Amp. CEE-form female connector is required. The four wire power cable (3P/G; Neutral is not required) should, for safety reasons, be connected to a mains switch. The external power supply and grounding should comply with local codes and regulations, this is not the responsibility of the Mobile manufacturer.
All specifications apply to measurements at the receptacle pins. Line voltage drops from the facility mains to the receptacle must be included in all power calculations; power range to be in +/- 5% of specified Voltage.
