摘要： A charged particle irradiation system that positions the beam at a target position to avoid irradiation of normal tissue includes an acceleration system 6 for extracting a charged particle beam, scanning magnets 24 and 25, and charged particle beam position monitors 26 and 27. On the basis of signals received from the charged particle beam position monitors 26 and 27, the control unit 70 calculates a beam position at a target position and then controls the scanning magnets 24 and 25 so that the charged particle beam is moved to a desired irradiation position at the target position. The control unit 70 corrects the value of an excitation current applied to each of the scanning magnets 24 and 25 on a specified cycle basis on the basis of information about the position and the angle of the charged particle beam.

摘要： A particle therapy system, as one example of a particle beam irradiation system, comprises a charged particle beam generator and an irradiation field forming apparatus. An ion beam from the charged particle beam generator is irradiated to a diseased part in the body of a patient through the irradiation field forming apparatus. A scattering compensator and a range modulation wheel (RMW) are disposed on the upstream side in a direction of beam advance and are movable along a beam axis. The movement of the scattering compensator and the RMW adjusts a size of the ion beam entering a scatterer device, whereby a change in scattering intensity of the ion beam in the scatterer device is adjusted. As a result, a penumbra in dose distribution is reduced and a more uniform dose distribution in a direction perpendicular to the direction of beam advance is obtained in the diseased part.

摘要： The present invention provides an increased degree of uniformity of radiation dose distribution for the interior of a diseased part. A particle beam therapy system includes a charged particle beam generation apparatus and an irradiation apparatus. An ion beam is generated by the charged particle beam generation apparatus. The irradiation apparatus exposes a diseased part to the generated ion beam. A scattering device, a range adjustment device, and a Bragg peak spreading device are installed upstream of a first scanning magnet and a second scanning magnet. The scattering device and the range adjustment device are combined together and moved along a beam axis, whereas the Bragg peak spreading device is moved independently along the beam axis. The scattering device moves to adjust the degree of ion beam scattering. The range adjustment device moves to adjust ion beam scatter changes caused by an absorber thickness adjustment. The Bragg peak spreading device moves to adjust ion beam scatter changes arising out of an SOBP device. These adjustments provide uniformity of radiation dose distribution for the diseased part.

摘要： The invention provides a charged particle therapy system capable of increasing the number of patients treated. An irradiation filed forming apparatus for irradiating a charged particle beam extracted from a charged particle beam generator to an irradiation target includes an RMW device. The RMW device comprises a housing and an RMW disposed within the housing. A rotary shaft of the RMW is rotatably mounted to the housing. The RMW device is detachably installed in an RMW holding member provided in a casing of the irradiation filed forming apparatus. The housing can be placed in contact with the RMW holding member, and hence positioning of the rotary shaft of the RMW to a predetermined position can be performed in a short time. This contributes to cutting a time required for treatment per patient and increasing the number of patients treated.
