7.5 QA Scanning
Perform a QA scan of the phantoms to ensure all coils are working to specification. The QA scan must be
completed for 16ch and 10ch configurations of the Vanguard.
Note: QA scan test results should be determined using the procedure outlined below in Test 1 and 2 and
entered into the Quality Assurance SNR Section in the Installation Verification Checklist which can be
found in the Appendix.
Sentinelle Medical recommends that the coils be checked for imaging integrity on a regular basis, by
performing the Multi-Coil Quality Assurance (MCQA) procedure. The phantoms used for the QA scan are
part of GE’s System Phantom Set. The instructions below only apply to the Sentinelle Vanguard system.
Note: If bubbles are apparent in the phantom, tap the outside of the phantom until these bubbles disappear.
Tools Required
The tools required to complete the MCQA procedures are outlined below in Test 1 and 2 are listed in
