Assignee: HITACHI, LTD.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 1:
2. The particle therapy system according to claim 1, further comprising:
an irradiation time recording unit configured to record irradiation time at which the particle beam is emitted;
a tracking target position measurement unit configured to measure a position of a tracking target being irradiated with the particle beam;
a tracking time recording unit configured to record tracking time when the position of the tracking target is measured; and
a moving body tracking control system that is configured to determine 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 that is configured to output a signal for permitting extraction of the particle beam to the irradiation control system when determining that the position of the target is within the range,
wherein the dose calculation system is configured to calculate 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
wherein the irradiation control system is configured to control the particle beam based upon the signal generated by the moving body tracking control system.
