• a patient restraint operable to restrain the patient relative to the treatment apparatus, at least a portion of the patient restraint being colored;
• a camera system operable to obtain images of the patient and the patient restraint;
• and
• a model generation module operable to process images obtained by the camera system, identify portions of the images corresponding to the color of the colored restraint, and generate a model of the surface of a portion of a patient appearing in the images utilizing portions of images which are not identified as corresponding to the color of the colored portion of the restraint.
