Abstract
A bolus and final collimators are inserted into an apparatus for fixing radiation beam irradiation field forming member, fixed on the front end of radiation beam irradiating section within a rotation gantry, through grooves of a frame, and pushed in by a door until they reach a specified position determined by the existence of a back panel. Through this arrangement it is possible to easily perform an exchange of boluses and final collimators which is required each time therapy is renewed for a patient, and to accurately determine the position of new bolus and final collimators.
