Abstract
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.
