GE ULTRASOUND QUALITY ASSURANCE
ACR ULTRASOUND ACCREDITATION PROGRAM
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 second
phase 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 measurement
accuracy when a QA program is initiated for a scanner. It is not required that these factors be
reassessed 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 current
commercially available units.
2. Test Frequency
QA tests should be done at least semiannually for each scanner as part of the quality
assurance program for the site. Test results must be documented so that trends in equipment
performance can be identified and appropriate corrective action taken.
3. Transducers
On an ongoing basis, tests should be done using two probes commonly used with any
scanner employing more than one transducer. It is recommended that these be of different
scan formats such as one linear (or curvilinear) array and one sector (mechanical, phased or
vector).
4. Data to be Submitted for Accreditation
For each scanner, submit the QC Summary (Section G of the Full Application) which shows
the data acquired from one of the semiannual tests. The QC Summary should document
results from testing the transducer (which includes two probes with different formats). Data
should be taken from testing of the transducer which is used for the most frequently occurring
examination at the site.
