Overview
Exact
patient positioning in radiotherapy is crucial
for accurate targeting of tumors and sparing of
organs-at-risk. The aim of this project is to
develop a camera based guidance system for
patient positioning and monitoring. The
so-called smARtsKin system is also
capable of displaying patient support devices to
check for potential collisions with the linear
accelerator prior to treatment as well as
continuously monitoring the patient’s position
and breathing and therefore can considerably
improve patient safety.
The heart of the approach is based on augmented
reality (AR) technology. The smARtsKin system
superimposes relevant patient contours onto
real-time camera feeds of the patient during
set-up and treatment to visualize differences
between the planned treatment position and the
current position of the patient. Using this
approach, patient misalignment and deformations
as well as miss-positioned immobilization
devices can be detected and corrected either
prior to corrections based on on-board
volumetric imaging or during treatment if
continuous monitoring indicates patient
movement. A prototype of the system has been
tested and improvements such as the integration
of real-time surface measurements with the
infrared Kinect camera are work in progress.
