GE ULTRASOUND QUALITY ASSURANCEACR ULTRASOUND ACCREDITATION PROGRAM

The ACR Ultrasound Accreditation Program evaluates qualifications of personnel, equipment,image quality and quality control measures. It is believed that these are the primary factorsimpacting the quality of patient ultrasound imaging.

The Ultrasound Accreditation Program is carried out through the mail (paper submission), withrandom on site reviews performed as needed for validation or clarification.

PROGRAM GOALS

• Improvement in the quality of ultrasound performance.• Provision of educational information by raising awareness of ultrasound issues.• Recognition of ultrasound facilities which meet program objectives.• Collection of national data about the practice of ultrasound.

DEFINITION OF AN ULTRASOUND FACILITY

• Ultrasound section within a hospital• Ultrasound service offered in an outpatient setting, e.g., office, multispecialty clinic, or

imaging center• Mobile ultrasound service

A separate application is required for each location of ultrasound practice.

ULTRASOUND ACCREDITATION PROCESS

The ultrasound accreditation process consists of three parts which must be completedsuccessfully in order to receive accreditation.

Application – requests credentials of physicians and sonographer personnel.Quality Control Evaluation – requests information about ultrasound quality control.Clinical Image Evaluation – requests specific types of normal ultrasound exams; plus normal andabnormal exams for vascular accreditation.

QUALITY CONTROL EVALUATION

1. A quality assurance (QA) program should be in place for each scanner in the facility.

The quality assurance program must be directed by a medical physicist or by the supervisingradiologist or physician who may appoint an appropriate designee to oversee the program.There must be program documentation which describes the goals of the quality assuranceprogram and the responsibilities involved.

The person responsible for the quality assurance program must work with the preventivemaintenance professional. Routine quality control testing must occur regularly; a minimumrequirement is semiannually. The same tests must be performed during each testing period sothat changes can be monitored over time and effective corrective action can be taken. Testingresults, corrective action, and the effects of corrective action must be documented andmaintained on site.


QUALITY CONTROL EVALUATION (continued)

The QA program must evaluate at least the following items in Gray-Scale Imaging Mode.Specific QC data will be collected as part of the Full Application that is submitted in the secondphase of the accreditation process.

• System sensitivity and/or penetration capability.• Image uniformity.• Photography and other hard copy recording.• Low contrast object detectability (optional).• Assurance of electrical and mechanical safety.

In addition, it is recommended that users verify vertical and horizontal distance measurementaccuracy when a QA program is initiated for a scanner. It is not required that these factors bereassessed during QC testing.

These items may be assessed using commercially available phantoms. At the present time,there is no single phantom that is preferred; users should select a phantom from currentcommercially available units.

2. Test Frequency

QA tests should be done at least semiannually for each scanner as part of the qualityassurance program for the site. Test results must be documented so that trends in equipmentperformance can be identified and appropriate corrective action taken.

3. Transducers

On an ongoing basis, tests should be done using two probes commonly used with anyscanner employing more than one transducer. It is recommended that these be of differentscan formats such as one linear (or curvilinear) array and one sector (mechanical, phased orvector).

4. Data to be Submitted for Accreditation

For each scanner, submit the QC Summary (Section G of the Full Application) which showsthe data acquired from one of the semiannual tests. The QC Summary should documentresults from testing the transducer (which includes two probes with different formats). Datashould be taken from testing of the transducer which is used for the most frequently occurringexamination at the site.

HOW GE ULTRASOUND CAN HELP

The ACR Quality Control Evaluation and Program is where we can help our customers with GEQuality Assurance Evaluations (PMs).

New QA procedures are being written and tested to ensure that we incorporate the items that arerequired by the ACR. It may be a slightly new mindset for the Field Engineer as it will require alittle more documentation so that the customer maintains records necessary to determineperformance trends.

The new QA testing that can be offered by GE Ultrasound will consist of:

• System QA Procedure – A Job Card style document with checks, tests and space available toattach hard copy images for archival.

• QA Reference Manual – A detailed explanation of each check and test in the procedure. TheFE can refer to this if necessary.

• ACR Quality Control, Section G &H – Electronic versions of the official ACR paper submittalforms. We have permission from the ACR to reprint this part of the accreditation application.

How I envision this to work. All forms are electronic and will be on a CD:

• FE opens up System QA Procedure on field laptop.• FE performs appropriate checks and tests in the System QA Procedure.• FE makes necessary entries on the electronic form.• FE makes required hard copy images.• At the completion of the System QA Procedure, FE prints out the procedure, attaches the hard

copy images in the appropriate place on the printout.• While the FE completed the System QA Procedure on the laptop, the ACR Quality Control –

Section G (and maybe H) forms are filled in automatically. The FE prints out the ACR formsand signs them.

• The FE gets customer approval and leaves the completed System QA Procedure and ACRforms with the customer, with instructions that Quality Control – Section G & H can be used tosubmit for ACR approval with the remainder of the paper application required by the ACR.

• Customer should also be reminded that retention of records for performance trends is critical,if not mandatory.

NOTE: One extra thing we could do (for all or warranty/contract customers) is provide a QCbinder with divider tabs. This would allow the customer to maintain records of preventative andcorrective maintenance for trending and audit purposes.

OPTIONAL DATA FOR THE LOGIQ α200 OR LOGIQ 200 PRO

The remainder of the checks are optional steps that can be accomplished by the field engineer or the customer.While the following do not directly affect image quality, it may be good information to archive in the event thatthe system would need to be restored after a catastrophic system failure.

PRESETSAll system presets can be saved on a 128 Mbyte MOD through the SETUP>UTILITY Menu.

Press the SETUP MENU Key. Arrow down to USER UTILITY and press SET.

In the USER UTILITY Menu, ensure that a MOD has been formatted using Media Initialize.

Perform thye following procedures:Preset Data BackupOB User Table BackupOB Trend Data Backup.

Label and date the MOD accordingly and have the customer store it in a safe place.

Preset data backed up at the request of the customer.

Customer chose not to back up preset data.

LOGIQ 200 PRO


LOGIQ α200

This process is more intensive than a LOGIQ 200 PRO. No device is available the save the presetselectronically. Each screen must be displayed on the monitor and a print taken of that display. The printscan then be stored in a safe place for future reference.

Ask the customer which menus are important for them to archive in the rare case of a catastropic failure.

PRESETSTo go directly to the system setup parameters pages, press Make prints of all System Setup Parameter pages.

Remember: Some pages may require two or more prints due to each applications presets and then foreach probe attached. Use the following items as a check list of what menus were printed:

Contrast Resolution. (OPTIONAL) QA Reference Manual Section 4-2 Step 6 & 7. Evaluatethe phantom contrast targets in the current scan. The point is not how any ONE of the targets lookbut how well defined they are from each other, and from the background material.

Record the following information for five of the contrast targets, if available in the phantom. If theyare not available, indicate with N/A:


Object Depth

Object Size

Object Contrast *

Use the Echo Level function by Freezing the image. Press the Measurement key three (3) times to assess the gray scale contrast level.A 3 cm square box appears in the image area.Position the box in the center of the contrast object.Press Set.Record the resulting number as the Object Contrast in the chart above.

Adjust the system settings to produces a clean image.Wipe all the gel from the probe face, and set the probe in its holder. With transmit power at a fixedvalue, adjust the overall gain, until the far field image (beyond 3cm) begins to fill with noise. Reducethe overall gain until the last of those noise “speckles” disappear.
