Alignment Tools and Devices
Proper alignment requires the following:
Precise alignment devices to record the actual alignment using
adaPTinsight: in case adaPTinsight is used for computing the initial corrections,
the initial position of the tumor is indicated on the CT scan in the TPS. Next the
treatment plan and the CT scan are transferred to adaPTinsight. The
adaPTinsight software computes the correction vector from the treatment plan,
the CT scan, and two orthogonal radiographic images acquired in the TR.
The adaPTinsight software communicates the correction vector automatically to
the TCS, which supplies the correction data to the positioning devices, until the
optimal alignment is reached. For detailed information on alignment tools, refer
to section "Patient Alignment Devices" on page 12-7.
Precise alignment data: you can obtain such data for all non-eye treatments
using the PPVS application (e.g., adaPTinsight).
For an overview on how to use the PPVS data, refer to the following:
For adaPTinsight data, refer to section "Alignment Correction Calculation Tool:
adaPTinsight" on page 12-3.
For a detailed description on how to compute positioning corrections using any of the
PPVS systems, refer to the following:
adaPTinsight: refer to Chapter 50, “Calculating Corrections Using adaPTinsight”.
WARNING Make sure that a procedure is run regularly to check the correct
alignment of the Patient Position Verification System (PPVS).
