Fig 1. Setup of canine and camera for multibeam radiotherapy.

A) A close-up image of the tumor on the shoulder of this dog demonstrates where the Oxylite probes were placed within the tumor and normal tissue. On top of the tumor is a Cherenkov-transparent bolus. B) The camera was placed on the table behind the subject so the gantry would not interfere with the camera, and any table movements would maintain the same camera-tumor position. C) From the camera’s point-of-view, the tumor is visible.
