MOSAIQ User’s Guide
Auto-Setup You should only use Auto Setup as an approximate method to
position the linac to treat a patient. You cannot rely solely on
the electronic readouts to position the linac. You must verify
the linac position with an alternative method or methods.
Improper use of the auto setup feature could result in serious
injury to the patient. You should be in the treatment room, and
constantly monitor the treatment unit while you use Auto
Setup. You must be thoroughly familiar with the emergency
procedures to stop motions (disengaging motion enable
switches, pressing emergency off, etc.) before you use the autosetup
feature. If a collision condition appears likely, it is your
responsibility to stop motion and disengage the motion enable
switch or take other recommended action to stop motion as
recommended by the linac manufacturer (press the emergency
off).
Geometric
Tolerances
SEQUENCER only verifies geometric setup parameters to
within the specified tolerances. Do NOT rely on SEQUENCER
to verify the patient and linac setup position. Check the
treatment setup using the parameters specified in the Treatment
Field Definition dialog box.
Treatment Setup You cannot use SEQUENCER as the sole method to verify and
record the treatment setup. You must use an alternative method
or methods to verify and record the treatment setup in addition
to SEQUENCER.
Recording
Treatments
Always review all information in the Record Treatment dialog
box before saving it. Make sure that the correct patient and
treatment field appears. Make sure that the correct number of
monitor units appears as compared to the electronic and/or
mechanical monitor units readout on the linac. If the monitor
units value is not the same in SEQUENCER and the linac, then
record the monitor units value on the linac as a Note and
contact your department physicist immediately before you
continue the treatment.
