Chapter 14: Quality Assurance and
Maintenance
This chapter explains the Quality Assurance and Maintenance process for your system. To assure contin-
ued performance of this X-ray equipment, a periodic inspection program must be established. Daily
functional checks should be part of this program.
Quality Assurance Process
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 auto-
mated and require the acquisitions to be performed in the prescribed order.
Types of Quality Tests
There are two types of quality tests:
Detector Check: A Detector Test is a quick test to check for detector quality. This test can be part of a
daily check or completed if the detector was dropped or suspected to be 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: QAP is a complete quality test that requires taking exposures of a flat field phantom and a MTF
phantom. The results (pass or fail) are recorded in a results history summary. The QAP test can be per-
formed in approximately 15 minutes. A detector check is automatically performed as part of QAP.
When to Perform QAP
QAP should be performed
On a scheduled, weekly basis.
When the alert icon appears on the QAP button (Figure 14-1) located at the bottom of the Worklist or
Acquisition screens.
When there is a perceived loss of image quality.
When a critical detector bump event has occurred. (
