Title:
ENERGY MODULATION DEVICE, AND PARTICLE BEAM IRRADIATION APPARATUS, PARTICLE BEAM IRRADIATION METHOD, AND PARTICLE BEAM MEDICAL TREATMENT PLANNING APPARATUS USING SAID DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/032546
Kind Code:
A1
Abstract:
Provided are: a particle beam irradiation apparatus that makes it possible to shorten the distance between a patient and an irradiation field forming appliance of the particle beam irradiation apparatus; and an energy modulation device for use in the particle beam irradiation apparatus. This energy modulation device is for use in a particle beam irradiation apparatus 10 which transports, by using a beam transport line 2, charged particle beams extracted from an accelerator 1 and which performs irradiation by a scanning method by using scanning electromagnets 4, 5. In other words, the energy modulation device is a ripple filter 7. The ripple filter 7 comprises filter members 70 each having a plurality of opening parts 72 which penetrate in the thickness direction and through which at least some of the charged particle beams pass. Two or more of the filter members 70 are disposed so as to be laminated in the thickness direction.
