How to use this guide

Welcome to Numaris, the user software for operating the MRsystems:

o MAGNETOM Vision,o MAGNETOM Impact,o MAGNETOM Impact Expert,o MAGNETOM Open

Please note: In the context of this handbook the product name:

o MAGNETOM Open also includes the Open viva and Open viva #Psystems,

o MAGNETOM Vision also includes the Vision plus systems,o MAGNETOM Impact also includes the Impact plus systems,o MAGNETOM Impact Expert also includes the Impact Expert plus

systems.

Keywords To help you locate specific operating steps, the description of con-cepts is identified by keywords written in bold letters in the leftmargin of the text. All keywords are listed in the index.

Please note: The measurement protocols, pulse sequences, coilsand parameters shown in the manual depend upon the systemand application and are only to be used as examples.

The layout of the guide

Chapter The chapters are organized according to the sequence used in list-ing the functions in the menus. Each function is allocated a chap-ter identified by a letter and a number. For example : chapter B.3Changing the measurement parameters = Measurement Change.

Part The chapters are combined into parts just as the individual func-tions are grouped into main function groups. For example : Part BMeasurement = main function group Measurement.

Summary chapter The functions described in a new part are defined and summa-rized in the first chapter of a part.

Index The index has been appended at the end of this manual.

Should you have any suggestions or proposals for improvement,please tell us. We will gladly incorporate your suggestions in thenext update.

Thank you for your cooperation.

Please note: The user is responsible for any changes made to thestandard settings.

The following settings are possible:

New Study Study description , Accession number or Body part examinedcan be set for a new study.

Patient Renew Do not set up a New study for the updated patient. Change the pa-tient's weight for the following examinations, without starting aNew study.

A.1Selecting a patient

When you select a patient with Patient Select, his/her imageswill be displayed in the active segment. You can also scrollthrough patient list, series list, or image list.

The patient actually selected then becomes the active view patient.

Active view patient The active view patient is the patient corresponding to the imagedisplayed in the active segment.

You can select a specific series or image of the patient, as required.

Use the function button in the function field of the control area in-stead of the menu for fastest access to the function.

Sorting the patient list

The patient list of the hard disk STORE is sorted chronologicallyaccording to the registration date: The most recent date appears atthe top. The patient list of an optical disk is sorted alphabetically.

You can change how the patient list is sorted, i.e. alphabetically orchronologically. For that purpose, select the SortPatients pro-gram in the System Run function (page K.23).

Alternative 1: Display a patient with standard image

Standard image The program automatically displays either the first or the centerimage of the series selected. You can set the standard image as thedefault parameter with the Display Screen function (page J.18).Please note: The setting will not affect localizer images with theirdifferent slice orientations.

Double-click the corresponding line in the patient list.The standard image of the first series of the patient selected is dis-played in the active segment. Both the list and the function win-dow will be closed, if the list is not pinned.

Alternative 2: Open the series and /or image list

To select a patient from the list and to open his/her series list :

You select the current patient with the Patient Current function.One of the images for this patient will be displayed in the activesegment.

If you are running automatic image display, the images of the cur-rent patient will be displayed automatically (chapter J.5).

Current patient The current patient is the patient last registered as a result of thefunctions Patient Register or Renew. Since the data of the cur-rent patient are always saved to STORE, the hard disk is automat-ically selected as the storage device when you call this function.

Use the function button in the function field of the control area in-stead of the menu for fastest access to the function.

Weight: Best estimate minus 10 %In order to avoid excessive RF exposure: Make a conservative estimate ofthe patients weight, i.e. it is better to underestimate than to overesti-mate.

The English abbreviation is used forthe month (3 upper or lower-caseletters)

Notice

Please enter the correct weight of the patient. The SARcomputation (SAR chapter B.13, not MAGNETOM Open) is based

Dynamic image numberingThe dynamic image numbering allows you to individually set im-age numbering in the Register window for the following mea-surements.

Depending on the image orientation, you can determine whetherthe images should be numbered in the ascending or descendingorder.

You can assign the image numbering for the respective orienta-tions for each Body part examined (page A.36).Please contact your application specialist for the respective set-tings. If dynamic image numbering is enabled, AAA is set by de-fault. That is:

Use the Patient Modify function to modify various patient data ofa patient (exception: weight of patient page A.55). You canchange the data for either all or only part of the images. The datafor future images are changed with Patient Renew (chapter A.5).The image sort is changed with the Series Arrange function(chapter C.3).

The data of the current patient cannot be changed while the mea-surement is in progress.

The modified data are shown in the image text (in the image textfield or in the active image), when an image for a modified pa-tient is displayed in the active segment.

Please note: The function does not apply to preregistered patientswithout images. Data for preregistered patients may be modifiedonly using the Patient Renew function (chapter A.5).
