摘要： A particle therapy system capable of confirming energy of an accelerated charged particle beam before the charged particle beam is irradiated to an irradiation target. A beam position monitor is disposed in a synchrotron, and a cavity voltage monitor is associated with an RF cavity for acceleration. An ion beam orbiting within the synchrotron is accelerated with application of an RF voltage applied to the RF cavity and is extracted from the synchrotron with application of an RF voltage applied to an RF knockout electrode. Based on a cavity voltage signal detected by the cavity voltage monitor, a frequency counter measures the frequency of the RF voltage applied to the RF cavity. Based on a voltage detected by the beam position monitor, a beam signal processing unit measures the position of a beam orbit. Based on the frequency of the RF voltage and the position of the beam orbit, the energy judgment processing unit determines whether energy of the ion beam after the end of the acceleration is normal or abnormal.

摘要： A charged particle beam irradiation system and a charged particle beam extraction method which can prevent erroneous irradiation of a charged particle beam in the direction of advance of the charged particle beam. The system and method are featured in stopping supply of an ion beam to one or more of a plurality of angle zones in each of which a target dose is attained, the angle zones being formed by dividing an RMW in a rotating direction thereof, and in allowing the supply of the ion beam to one or more other angle zones in each of which a target dose is not yet attained. The invention can easily adjust beam doses at various positions in an affected part of the patient body in the direction of advance of the ion beam, and can greatly reduce the probability of erroneous irradiation that the beam dose becomes excessive or deficient at the various positions within the affected part of the patient body in the direction of advance of the ion beam.
