Patent ID: 7319231

Claim:
A particle beam therapy system comprising: a charged particle beam generator for emitting a charged particle beam; a plurality of treatment rooms in each of which an irradiation unit for irradiating the charged particle beam is disposed; a charged particle beam transport apparatus having a plurality of beam paths, communicated with said charged particle beam generator, and transporting the charged particle beam emitted from said charged particle beam generator separately to said respective irradiation units in said plurality of treatment rooms; a plurality of first manual input devices provided correspondingly to said plurality of treatment rooms for generating irradiation ready signals, respectively; a plurality of second manual input devices provided correspondingly to said plurality of treatment rooms for generating irradiation start signals, respectively; a control system for deciding the sequence of introducing the charged particle beam to said plurality of treatment rooms based on said respective irradiation ready signals corresponding to said treatment rooms generated by said first manual input devices, and forming the beam paths for introducing the charged particle beam, emitted from said charged particle beam generator, to the respective irradiation units in said treatment rooms in accordance with the decided sequence; and an emission start control unit for outputting an emission start signal based on said irradiation start signal generated by said second manual input device corresponding to said treatment room with top priority to which the charged particle beam is to be first introduced, after said beam path for introducing the charged particle beam to the irradiation unit in said treatment room with top priority has been formed by said control system.
