Pre-Treatment Warnings<br />

Every time you start treatment delivery, SEQUENCER makes a series of initial checks. The<br />

following is a description of each check, in the order that SEQUENCER makes them, and the<br />

warning message that appears if the system finds a discrepancy.<br />

Field Treated Today!<br />

Continue?<br />

Fractions will be<br />

Exceeded! Continue?<br />

Field dose is<br />

undefined. Continue?<br />

Treatment field is not<br />

associated with<br />

prescription site.<br />

Continue?<br />

A dose site<br />

coefficient has either<br />

not been defined or<br />

set up so that the<br />

treatment of this field<br />

will not contribute<br />

any dose to the<br />

prescription site.<br />

Continue?<br />

Dose Will Be<br />

Exceeded by #!<br />

Override?<br />

Treatment Machine<br />

Mismatch! Override?<br />

This message appears as a warning if you are about to treat a<br />

patient field that was already treated today. Click Yes if you<br />

still want to treat the field(s)<br />

This message appears when you are about to exceed the<br />

number of fractions prescribed.<br />

This warning appears if the selected field does not have a dose<br />

value greater than zero (0) and your department is configured<br />

to receive dose check warnings. You can either cancel the<br />

approval or continue with the approval process and not change<br />

the dose value.<br />

This warning appears if the field selected is not associated with<br />

a parent Rx site and your department is configured to receive<br />

dose check warnings.<br />

This warning message appears if the field is associated with a<br />

parent Rx site, but does not have an effective dose site<br />

coefficient.<br />

This warning message appears when you are about to exceed<br />

the prescribed total dose. If you still want to treat the field,<br />

click Yes, then type your user name and password in the<br />

approval dialog box and press Enter to override the warning.<br />

Only users with override privileges can exceed the prescribed<br />

total dose.<br />

This warning message appears when you are about to treat a<br />

patient on any linac other than the one defined in the patient's<br />

Treatment Field Definition. If you still want to treat the field,<br />

click Yes, then type your user name and password in the<br />

approval dialog box and press Enter to override the warning.<br />

Only users with override privileges can treat on a linac that is<br />

not specified in the setup. If SEQUENCER still does not<br />

recognize the linac you are about to use, the message<br />

"Unknown Machine. Exiting." appears and you must exit the<br />

dialog box. You cannot treat on a linac that is not<br />

characterized. The machine mismatch check is userconfigurable<br />

at installation.<br />
