Patent number: 10596394Abstract: A system is disclosed that includes a radiation therapy device with a gantry. The radiation therapy device is configured to deliver a radiation beam at an angle determined by orientation of the gantry. Also, a pair of radiation detectors are located at a fixed position to receive radiation originating from the radiation beam. Each of the radiation detectors in the pair generate differing responses to the radiation beam at the angle. The system further includes computer hardware configured to perform operations that determine the angle of the gantry utilizing the differing responses from the pair of radiation detectors.Type: GrantFiled: July 28, 2017Date of Patent: March 24, 2020Assignee: Sun Nuclear CorporationInventors: William E.

Patent number: 9480861Abstract: Data from a first radiation detector and a second radiation detector can be used to determine a radiation dose pattern delivered to a radiation target from a radiation source. The first radiation detector can be positioned to intercept ionizing radiation directed from the radiation source toward the radiation target before the ionizing radiation has impinged on the radiation target and the second radiation detector can be positioned to intercept the ionizing radiation after the ionizing radiation has passed through the radiation target. Methods, systems, articles of manufacture, and computer program products are described.Type: GrantFiled: April 3, 2015Date of Patent: November 1, 2016Assignee: SUN NUCLEAR CORPORATIONInventors: Jeffrey M. Kapatoes, William E. Simon, Jakub Kozelka

Patent number: 8321179Abstract: A three dimensional radiation measurement scanning system includes a circular drive operable with horizontal and vertical drives for moving a radiation detector through first, second and third orthogonal axes in a three dimensional scanning of the detector in a water tank. Motor are coupled to the drives and activated by a controller for providing the movement of the radiation detector which providing radiation field sensing signals for locations of the detector throughout the tank. A reference detector is fixed for comparing its radiation field measurements with those of the scanned radiation detector. An offset mount carries the radiation detector allowing it to be extended beyond the circular ring gear during horizontal movement of the radiation detector and thus position the radiation detector at wall surfaces of the water tank.Type: GrantFiled: July 21, 2010Date of Patent: November 27, 2012Assignee: Sun Nuclear CorporationInventors: William E.
