Chapter 11: Quality Assurance Process and
Maintenance
This chapter explains the Quality Assurance and Maintenance process for the system. To assure
continued performance of the system, 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

When to Perform Quality Tests

Types of Quality Tests
There are two types of quality tests:
•
Detector Check: A quick test to check detector quality. 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.
