Abstract:
Proton therapy is a successful treatment for lesions that are hard to treat using conventional radiotherapy, as
the radiation dose to nearby critical structures can be tightly controlled. To realise these advantages, the patient needs to be accurately positioned, and monitored during treatment to ensure that no motion occurs. iThemba LABS uses a fixed beam-line, and moves the patient using a suitable positioning device. In this paper, we discuss several aspects the stereo vision based system used to both determine the position of the patient in the room, and to monitor the patient during treatment.
