Chapter A8: Quality Assurance Process and
Maintenance
This chapter explains the Quality Assurance and Maintenance process for the GE Portable DR Detector.
To assure continued performance of the GE Portable DR Detector, a periodic inspection program must be
established. Daily functional checks should be part of this program.
The Quality Assurance Process (QAP) consists of a series of tests that should be performed weekly on
your system to quantify image quality. Many of the background tasks in this procedure have been
automated and require the acquisitions to be performed in the prescribed order.
Topics covered include:
• Types of Quality Tests
(p. A8-1)
• When to Perform Quality Tests
(p. A8-2)
• Quality Test Preparation
(p. A8-2)
• Perform Detector Check
(p. A8-3)
• Perform QAP
(p. A8-5)
• Result History
(p. A8-11)
• Maintenance and Cleaning
(p. A8-12)
Types of Quality Tests
There are two types of quality tests:
• Detector Check: A quick test to check detector quality if the detector was dropped. Detector Check
does not require making exposures and the pass or fail results are not included in the results history.
The Detector Check test can be performed in approximately 30 seconds.
• QAP: A full QAP test that requires taking exposures of a flat field phantom. The results (pass or fail) are
recorded in a results history summary for service personnel review. The QAP test can be performed in
approximately 15 minutes.
The QAP test includes all the tests that are performed for Detector Check and tests additional
factors.
