  • Publication number: 20190175950
    Abstract: The radiation detection device includes a plurality of radiation detectors arranged in a row and is inserted into the body of patient subjected to the X-ray therapy. An X-ray detection signal (photon) is output from each of the radiation detectors that detects the X-ray applied to the patient. The dose rate measurement device separately connected to each of the radiation detectors obtains the dos rate at the position of each radiation detector based on the signals. The irradiation direction determination device determines whether the row of radiation detectors matches the irradiation direction of the X-ray using the dos rate obtained by each of the dose rate measurement devices. When the row of radiation detectors matches the irradiation direction, the energy distribution analysis device obtains an energy distribution using the dose rate at the positions of the radiation detectors by applying, for example, an inverse problem analysis called an unfolding method.
