発明の名称 (英語) DYNAMIC TUMOR RADIATION TREATMENT APPARATUS AND DYNAMIC TUMOR RADIATION TREATMENT PROGRAM
発明の概要(英語) [PROBLEMS] To provide a dynamic tumor radiation treatment apparatus and program for detecting the position of a tumor with high accuracy without imposing a burden on the patient, continuously detecting a tumor with high detection efficiency, and effectively irradiating only a malignant tumor with radiation to reduce the radiation exposure dose. [MEANS FOR SOLVING PROBLEMS] A dynamic tumor radiation treatment apparatus comprises gamma ray detecting means (20) for detecting an annihilation gamma ray, displacement threshold storage means (32) for storing the threshold of counting rate, gamma ray counting rate computing means (41) for computing the counting rate according to the detection signal of an annihilation gamma ray, threshold comparing means (43) for comparing the counting rate of annihilation gamma rays acquired from the gamma ray counting rate computing means (41) with the threshold of the counting rate acquired from the displacement threshold storage means (32), tumor position judging means (44) for judging whether or not the tumor displaces out of the radiation irradiation spot, and irradiation control means (45) for making a control to stop radiation irradiation or outputting a stop command signal.
