Abstract
The disclosure concerns radio-therapy machines and installations. The precise position of a patient is verified by means of a device mounted on the movable arm of a mount with isocentric motion. This device includes a system for scanning by a light beam. The position of the source of this light beam corresponds to the position of radiation source. The device further has a system for the optical detection of the point of impact of the light beam on the patient. These two systems enable the position of the point of impact to be determined by means of a data-processing system.
