Correcting the Setup Position
Corrections to the Setup position are computed using adaPTinsight. For detailed
information on how to use adaPTinsight, refer to the adaPTinsight documentation
listed in the Delivery Note.
As the Setup position is used to confirm patient alignment on the couch, the only
settings that can be corrected (adjusted) for this position are the six axes of the PPS.
The allowed setup corrections include the following PPS axes:
PPS Delta x (cm)
PPS Delta y (cm)
PPS Delta z (cm)
PPS Delta Rotation (degree)
PPS Delta Pitch (degree)
PPS Delta Roll (degree)
To correct the Setup position:
1. Input the correction values using the terminal in the TR (refer to Section
"Inputting the Setup Corrections" on page 49-6).
2. Implement the corrections (refer to Section "Implementing the Corrections" on
page 49-6) using the hand-pendant or the remote positioning controls.
WARNING As a Radiation Therapy Technologist (RTT) it is your responsibility to
verify the appropriateness of the corrections generated by the Patient
Position Verification System (PPVS).
WARNING After applying and implementing the corrections calculated by the
Patient Position Verification System (PPVS) software (e.g.,
adaPTinsight), it is recommended to take a new set of X-ray images to
verify proper positioning of the patient.
