When to Perform Quality Tests
QAP should be performed:
• On a scheduled, weekly basis.
• When the alert icon appears on the QAP button (Figure 11-1).
• When there is a perceived loss of image quality.
NOTE: When scheduling QAP tests, plan 15-20 minutes to perform the test. One portion of the test requires
that the system be powered on and in an idle state (i.e., without exposures) for at least 10 minutes.
The 10 minute idle period is based upon the time from the last exposure prior to performing QAP
or system start up. The rest of the test requires approximately 5 minutes to complete.
