<p>PROBLEM TO BE SOLVED: To provide a radiotherapeutic apparatus which achieves an easier access thereto by a patient with a smaller occupying volume and an inexpensive implementation. SOLUTION: The apparatus is equipped with a rotary gantry 16 installed rotatably about a rotating shaft 15, a synchrotron 22 which is provided with a particle generator 20 and a particle accumulation ring 21 and carried on the rotary gantry 16 and an irradiation field former 25 carried on the rotary gantry 16 so as to guide a corpuscular beam to an irradiation field along the irradiation axis 24 crossing the rotating shaft 15 and a deflection magnet 26 which deflects the corpuscular beam, supplied from the synchrotron 22, in the direction of the irradiation axis 24 to be guided to the irradiation field former 25.</p> |
