Performing the weekly QC test (Spatial Resolution and Artifact Test)
To identify artifacts and verify spatial resolution you must perform the
following test weekly or as needed to troubleshoot image quality problems.
1
Check the QC test image visually for artifacts: no significant disturbing
artifacts should be visible.
2
Check the spatial resolution.
The test film also shows three squares which each contains an oval. These 3 ovals
contain 3 groups, each having 5 dots. All five dots of each group must be visible
(use a magnifying glass and optimize viewing conditions).
3
Record the results on Drystar 5300 Chart 3 (Drystar 5300 'Artifacts and
Spatial Resolution Control Chart'). Refer to Appendix C
Charts' on page 199.
In case of significant artifacts, insufficient spatial resolution or failure of
any other recommended QC tests, the cause of the problem must be
identified, and corrective action must be taken before the Drystar 5300
can be used for any further clinical imaging.
