When to Perform Quality Tests
This section describes the recommended quality testing schedule and any other events that warrant
quality tests to be performed
Detector Check
Detector Check is used daily to check detector quality and anytime after an accidental drop.
After a detector drop, the system reports an error and displays a QAP alert icon (Figure A8-1) to indicate
that you should conduct a Detector Check test on the detector.
The Detector Check alert icon will remain until a Detector Check or QAP test is run.
QAP
QAP should be performed:
• On a scheduled, weekly basis.
• When the alert icon appears on the QAP button (Figure A8-1).
• 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.

Quality Test Preparation
Before starting quality tests, be sure to do the following:
• Close or suspend any open exams
• Close any exam being reviewed
• Clear all objects from detector and beam path (QAP only)
• Disconnect the unit from the charging outlet (exposures are not permitted while the unit is charging)
The QAP process begins when the QAP button is clicked. The button is located at the bottom of the
Worklist or Acquisition screen.
NOTE: QAP cannot be performed if an exam is open or being reviewed.
