Inputting the Setup Corrections
If small corrections to the Setup position are necessary, determined by a review of
the X-ray images, prepare the equipment for this Setup beam. For detailed
information, refer to Section “Equipment Preparation for a Setup Beam” on
page 33-2.
Note: Applying the corrections downloads the values to the Positioning Control Unit
(PCU) but does not move the PPS.
Implementing the Corrections
Use the wireless hand-pendant or remote positioning controls in Auto mode to
implement the corrections by moving the patient positioning devices to the
Corrected target position, as described in Chapter 9 and Chapter 11respectively.
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 When all alignment corrections have been applied and recorded by the
user, make sure that, according to treatment center procedures, a
second Radiation Therapy Technologist (RTT) verifies the entered
corrections.
WARNING Make sure that the DID flat panel arms are fully retracted before
attempting to move Patient Positioning Devices (PPDs) that can collide
with the flat panels.
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.
