Introducing Patient Positioning and

Alignment
This part assumes that the Radiation Therapy Technologist (RTT) is familiar with the
equipment (refer to Chapter 5, “Introducing Treatment Room Equipment").
At the time of treatment, positioning the patient takes place in the TR using the hand
pendant. The Digital Radiographs (DRs) are acquired at the time of preparation.
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 Therapy Control System (TCS).
Alternatively, the RTT can introduce these corrections manually from the TCS screen
in the TR. The therapist finally implements these corrections using the hand pendant
or the remote positioning controls.
This correction calculation can be iterated a number of times till a satisfactory
alignment is reached.
WARNING As a Radiation Therapy Technologist (RTT), it is your responsibility to
verify that the current machine geometrical configuration is matching
the prescribed configuration of the treatment plan (gantry angle, snout
position, Patient Positioning System [PPS] position).
