摘要：
A camera system 10 obtains stereoscopic video images of a patient 20 undergoing radio-therapy. The images are processed by a modelling unit which generates a 3D mesh model of the surface of a patient 20 being monitored, to determine the location of the patient. Additionally the patient monitoring system processes image data not utilized to generate the patient model to determine further information concerning the treatment of the patient 20. Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus 16. This can be facilitated by providing a number of spherical retro-reflective markers 30-40 on a treatment apparatus 16 and a mechanical couch 18 used to position the patient 20 relative to the treatment apparatus 16, and monitoring the presence and location of the apparatus markers in the periphery of the images obtained by the stereoscopic camera 10.
