Alignment Correction Calculation Tool:
adaPT
insight
The adaPTinsight software enables you to calculate the alignment corrections that
must be applied to the PPS to ensure a correct alignment of the patient in respect to
the isocenter. The adaPTinsight application calculates corrections for the GTR.
Note: The gantry based system is isocentric and shares the same geometric
reference as the X-ray Image Guided Radiation Therapy (IGRT) equipment.
In the Treatment Planning Room (TPR) all data that is useful for treatment preparation
is centralized, e.g., CT scans, RT Ion Plan information, etc. This is typically and most
efficiently done in the weeks or days before treatment.
In each TR where adaPTinsight is used, an adaPTinsight workstation with a monitor
is available from which the Digital Radiographs (DRs) are acquired at the time of
treatment.
Depending on the TR hardware configuration, 2D stereoscopic images are acquired
at the time of treatment using one or multiple imaging devices. Equally, and
optionally, 3D images can be acquired using a single 2D imaging device which rotates
around the volume to be imaged.
AdaPTinsight computes the correction vector using image registration techniques
and automatically transfers them into the TCS. Alternatively, the Radiation Therapy
Technologist (RTT) can introduce these corrections manually from the TCS screen in
the TR. The RTT finally implements these corrections using the hand pendant.
This correction calculation can be iterated a number of times until a satisfactory
alignment is reached.
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.
