Scan Using Alert Value Checking - GE Revolution CT User Manual

9 Scan Using Alert Value Checking

Use this procedure to scan using Alert Value (AV) Checking.
The CTDI or DLP value will be highlighted when the estimated dose for the protocol exceeds
vol
the AV value set for the system.
Adjust the scan parameters for the series until the exceeded AV value is below the prescribed
AV value. If the AV value is still exceeded after you click [Confirm], a confirmation message will
display. The scan cannot be confirmed until the AV value is no longer exceeded, or a user with
a Dose Check AV Exceeding user role has authorized the scan.
Performing a scan exceeding an AV value demands a high degree of consideration for
appropriateness. In most cases, you will click [Cancel] to go back to adjust parameters. If there
is a true diagnostic need to perform a scan exceeding an AV value, enter the diagnostic reason.
