RADIATION APPLYING APPARATUS

摘要

An X-ray irradiator (1) comprises an X-ray generating device (8), a head section (6), a manipulator (5), and a microwave source (4). The X-ray generating device (8) accelerates electrons emitted from an electron gun (9) by means of an accelerating tube (11) to cause them to hit against a target (10), thereby generating X-rays. The acceleration of electrons is effected b y microwaves. The X-ray generating device (8) is received in the head section (6). The head section (6) is attached to the front end of the manipulator (5 ). The manipulator (5) positions the head section (6) such that X-rays emitted from the head section (6) are applied to the affected part of a patient (P). The microwave source (4) is arranged at the base portion (5a) of the manipulator (5). The microwaves are transmitted from the microwave source (4 ) to the accelerating tube (11) through a waveguide (12).
