Performance Criteria and Corrective Action
Performance criteria: 5% and 95% grayscale patches should be visible.
Corrective Action: Ensure the viewing conditions are appropriate. Remove any objects that are reecting an unac-
ceptable glare.
If problems persist the REGIUS Console CS-3/CS-7 will need to have service to address the issue.
The source of the problem shall be identied and corrective action shall be taken before further patient imaging is
performed by use of that monitor. If the problematic monitor can be replaced by an alternative monitor, replace it and
repeat the test. If the new combination passes the test, patient imaging may continue using the alternative monitor.
