Abstract:
1. A particle beam therapy system comprising: a plurality of treatment rooms; a particle beam transport path that connects an accelerator with each of the plurality of treatment rooms; a switching device, provided in the transport path, that switches the orbits of a particle beam emitted from the accelerator, in such a way that the particle beam is supplied to one of the plurality of treatment rooms; a respiration induction apparatus, provided in each of the plurality of treatment rooms, that induces the respiration of a patient, based on a desired respiration waveform; an irradiation apparatus, provided in each of the plurality of treatment rooms, that forms a supplied particle beam into an irradiation field corresponding to an irradiation subject and controls irradiation onto the irradiation subject, in synchronization with at least the desired respiration waveform; and a controller that, during concurrent irradiation in at least two treatment rooms from among the plurality of treatment rooms, performs synchronization control of the switching device and the respiration induction apparatuses in the at least two treatment rooms, wherein the controller (i) adjusts the cycles and the phases of the desired respiration waveforms in the at least two treatment rooms relative to one another so that irradiation times synchronized with the desired respiration waveforms in the at least two treatment rooms do not overlap with one another, and (ii) controls the switching timing of the switching device so as to switch the orbits of the particle beam between the at least two treatment rooms during the concurrent irradiation thereof, in accordance with the respective irradiation times of the at least two treatment rooms.
