ION BEAM EMITTING EQUIPMENT AND ION BEAM EMITTING METHOD

摘要

PROBLEM TO BE SOLVED: To increase the number of patients treatable using one rotary body whose thickness varies in the direction of rotation to change the energy of a passing ion beam. SOLUTION: The ion beam emitting equipment for treating a patient by applying the ion beam to the patient 32 comprises a beam generating device 1 for generating the ion beam, a beam irradiation nozzle 15 provided with a range modulation wheel 29 having prescribed distribution of thickness in the circumferential direction, and rotating on the path of the ion beam generated from the beam generating device 1 for controlling the range of the ion beam, and an irradiation control device 38 for controlling the beam generation accelerating operation of the beam generating device 1 according to the rotation phase of the range modulation wheel 29.
