|発明の名称||CORPUSCULAR BEAM CURING APPARATUS HAVING SEPARATION TYPE SNOUT|
PROBLEM TO BE SOLVED: To improve the operational efficiency of a corpuscular beam curing apparatus and also improve work efficiency and safety by high-accuracy registration by an X-ray CT apparatus in corpuscular ray treatment.
SOLUTION: This curing apparatus for curing a cancer by a charged copususcular beam is provided with a means for independently moving a patient collimator 6 and porous part (snout 4) constituting a radiation field forming device separately from the other components of the radiation field forming device and a beam transport system, a template 7 having the same shape as that of an opening part of the patient collimator 6 and porous 5 part (snout 4) or shaped so that the opening part is corrected by a distance (SSD) between a light source and the patient, a means for registering the template 7 to the cancer, a means for moving the patient to the radiation position while keeping constant the relative position of the patient and the template, and a means for coinciding the template 7 with the patient collimator 6 and porous 5 part.
