During external beam radiation therapy the linear accelerator rotates around the patient, who is lying on the treatment table, and administers concentrated radiation to the cancer. One problem that may occur during treatment is a collision with the linear accelerator and the patient; this results in the treatment being stopped and re-planned, which is a time and resource consuming process that affects both the radiation therapists and the patient. This study involves developing a tool that simulates the radiation treatment on a computer, before the patient is brought in for the actual treatment. This will allow radiation therapists to check for collisions and adjust the treatment plan prior to treatment delivery. This tool hopes to save time and avoid repetition of treatment planning, and its clinical use is currently being evaluated in order to determine its value and effectiveness. Since the start of its regular use in early 2015 it has proved to be very useful tool.

 

 

 

Xbox Kinect Integration:

Over the course of the 2014-2015 school year, a team of Computer Science students have been developing a program that will allow CT staff to capture 3D models of patients in real-time. These models will be used with the collision detection simulator and this program looks to replace the current method of taking physical measurements of the patients pose and extremities in order to estimate their 3D model.  This software is demonstrated in the following video:

Capstone project demo. This software uses an Xbox Kinect sensor to capture 3D models of patients, which can be used in external beam radiation therapy simulations to predict collisions.
