  • Vision system for radiotherapy machine control
    Patent number: 9878179
    Abstract: In various embodiments, a system for controlling radiotherapy equipment in a treatment environment includes a controller for receiving, from one or more image capture devices, data indicating the position of one or more objects in the treatment environment. Based on the position data, the controller defines one or more exclusionary zones from which the radiotherapy equipment is excluded. Each zone has a buffer area surrounding one or more of the objects. The controller further directs the radiotherapy equipment such that a radiotherapy treatment plan is delivered without the equipment entering into the exclusionary zones.
    Type: Grant
