Using the Override Feature
CHAPTER 10: SEQUENCER
You can override the out-of-tolerance interlock and treat a patient with settings different
from those in the prescription. SEQUENCER keeps a record of overrides and the credentials
of the user who approved them. Out of tolerance parameters appear highlighted in red.
Overrides are temporary changes.
1. Double-click the field to treat in the Treatment Delivery Table window.
2. Right-click press F4 in the Verified Treatment window, then click Override….
You can also press CTRL+O to open the Overrides dialog box.
3. Select the out of tolerance parameter that you want to override in the Overrides dialog
box, then press the SPACEBAR to tag it.
4. Type the reason for the override(s) in the Note field.
5. Type your password in the Password field.
6. Click OK.
The out of tolerance values that you overrode appear highlighted in yellow.
Recording Treatments
Temporary field changes, such as changing the couch geometric
parameters, do NOT invalidate the reference image for the selected
treatment field, which you can show behind the treatment geometry
in the Beam's Eye View dialog box.
Always examine all information in the Record Treatment dialog box, Composite Record
dialog box, or Record Port before you save. Make sure that the correct patient and treatment
field shows. Make sure that the correct number of monitor units appears as compared to the
electronic and/or mechanical monitor units readout on the linac.
CAUTION
Record Treatment Dialog Box
If the monitor units value on the linac is not the same as in
SEQUENCER, then type the linac monitor units value in the Notes
field of the Record Treatment dialog box. Contact your
department physicist immediately before continuing treatment.
The Record Treatment dialog box lets you record treatments. Verify that the information
that appears in the Record Treatment dialog box is correct before you click Record. You
can type notes in the Note field if necessary.
