Abstract:
1. A particle beam therapy system in which a plurality of treatment rooms, each of which has a respiratory induction apparatus for instructing a patient in respiration timing, are provided, in which based on respective phases of the respiration timings, determined in such a way as to be shifted from one another, the plurality of treatment rooms are divided into a plurality of groups, and in which in a time-sharing manner, particle beams are concurrently irradiated onto patients in the respective treatment rooms selected from the plurality of groups, wherein a controller is provided that performs a step in which a single treatment room, as an irradiation subject of time-sharing irradiation, is selected from a group having a plurality of treatment rooms among the plurality of groups, wherein the controller grades respective irradiation readiness degrees of the treatment rooms in said group having a plurality of treatment rooms and selects the single treatment room, based on the graded values, and wherein the irradiation readiness degrees are graded based on a total sum of square errors between a desired respiratory waveform and a real respiratory waveform.
