摘要： The present invention improves the accuracy of therapy by checking in real time whether an spread-out Bragg peak (SOBP) width agrees with a desired width during irradiation with a beam. The device for outputting a charged particle beam includes a charged particle beam generator 1 including a synchrotron 4; a range modulation device such as a range modulation wheel (RMW) 28 which forms a Bragg peak of an ion beam extracted from this charged particle beam generator 1; an irradiation device 16 which is located in the direction of ion beam propagation of this RMW device 28 and includes a dose monitor 31 for detecting a dose of the ion beam; and an SOBP width calculation device 73 which calculates ion beam Bragg peak formed by the RMW device 28 based on a detection value of the dose monitor 31.

摘要： A beam extraction process (interruption and restart) is appropriately performed when a failure occurs during irradiation of a spot group. A charged particle irradiation system includes a synchrotron 12 and a scanning irradiation unit 15 that scans an ion beam extracted from the synchrotron over a subject. The extraction of the ion beam from the synchrotron is stopped on the basis of a beam extraction stop command. Scanning magnets 5A and 5B are controlled to change a point (spot) to be irradiated with the ion beam, while the extraction of the ion beam is stopped. The extraction of the ion beam from the synchrotron is restarted after the change of the spot to be irradiated. When a relatively minor failure in which continuous irradiation would be possible occurs during irradiation of a certain spot with the beam, the extraction of the beam is not immediately stopped.
