I had an internship at Ion Beam Applications (IBA) in Louvain-la-Neuve, Belgium, in collaboration with Professor Benoit Macq of Université catholique de Louvain (UCL).


IBA produces proton therapy cancer treatment devices. I worked with the patient positioning system team of IBA to improve the patient envelope of the collision detection system for IBA’s proton therapy cancer treatment device. The system was tracking a preset as a larger-than-life box on the treatment bench as the patient envelope and producing many false negative notifications. In exploring the viability of tracking the patient's location and contours real time, I translated the position of the device parts detected in the room to the coordinates understood by the device. The device mesh generated with CGAL was compared to 3D Microsoft Kinect point clouds of the treatment room processed with PCL to calculate an affine transformation matrix.
