The QAP phantom is used to check:
•
Edge Sharpness/Resolution
•
Image Resolution Uniformity
•
Dynamic Range Level Accuracy
•
Signal Contrast
•
Contrast to Noise Ratio (CNR)
At the completion of QAP, system image quality status will be reported to the
operator and will display one of the following messages:
•
QAP has completed successfully. Image Quality is optimal.
•
QAP has failed. Image Quality is not optimal. Call GE Service.
•
QAP could not be executed. Please run application again or call GE Ser-
vice.
A successful status indicates that all the image quality parameter values are
within the system specification limits. A failed status indicates that one or more of
the image quality parameter values fall outside the system specification limits. If a
system fails QAP, operator is advised to call GE Service to make the proper sys-
tem adjustments or calibrations to regain optimal system image quality. Periodic
QAP tests are recommended to assure optimal system operation.
