How to Apply and Implement the Calculated Corrections
Click Validate on the adaPTinsight screen: the corrections supplied by adaPTinsight
are transferred to the PMS I
NTERFACE PANEL of the EQUIPMENT PREPARATION SCREEN
that is displayed on the TCS monitor in the treatment room.
If the corrections are filled out correctly and you deem them appropriate, click Apply
Correction.
Which corrections must be transferred depends on the selected position, as follows:
Setup position: enter all six corrections.
Treatment position: enter 6 corrections (if 2 X-ray images were acquired) or
only 3 translation corrections (if only 1 X-ray image was acquired).
Note: Applying the position corrections downloads the values to the Positioning
Control Unit (PCU) but does not move the PPS.
Next you have to implement that correction from the hand pendant.
If the entered correction is too big, an error message appears. In such case, check
correction computation or change the initial position.
Therefore it is important to position the patient fairly precisely during the pre-
alignment phase. The thresholds for this pre-alignment can be configured on the
TCS.
For detailed information, refer to the chapter that is relevant for the treatment room
in which you are working:
GTR: refer to Chapter 52, "Aligning a Patient in the GTR".
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.
