Failed Detector Check
If the system fails the Detector Check (Figure 11-7), call to schedule service. The system is operational,
although inspection and potential calibration are needed.
WARNING:
Image quality may be degraded if you continue to use a detector that has failed the
Detector Check tests.

Perform QAP
QAP involves tests requiring exposures with the flat field phantom. The Definium 5000 QAP kit includes a
flat-field phantom (Figure 11-8) sized to fit the collimator.
QAP tests require that the system be on and idle for at least 10 minutes.
