Classification: CPC A  G | IPC A  G

Claim 12:
13. The method for operating the particle therapy system according to claim 12, further comprising:
recording, by an irradiation time recording unit, irradiation time at which the particle beam is emitted;
measuring, by a tracking target position measurement unit, a position of a tracking target being irradiated with the particle beam;
recording, by a tracking time recording unit, tracking time when the position of the tracking target is measured;
determining, by a moving body tracking control system, whether a position of the target is within a predetermined range based upon the position of the tracking target measured by the tracking target position measurement unit, and outputting, by the moving body tracking control system, a signal for permitting extraction of the particle beam to the irradiation control system when it is determined that the position of the target is within the range;
calculating, by the dose calculation system, the position of the tracking target being irradiated with the particle beam, and the irradiation amount and irradiation position of the particle beam then by synchronizing the irradiation time and the tracking time; and
controlling, by the irradiation control system, the particle beam based upon the signal generated by the moving body tracking control system.
