Abstract: The particle beam irradiation room of the invention includes: an irradiation execution room in which a patient table having a detachable-attachable top board and an actuation device for actuating the top board is mounted, and that is surrounded by a shielding wall; a passage formed in the shielding wall on its side where a pre-room for positioning the patient relative to the top board is located, in a form that allows the patient positioned relative to the top board to pass straight to the irradiation execution room by a transport apparatus; and a shielding door at the irradiation-room entrance located on a side of the passage toward the pre-room, for shielding against a leakage radiation at the radiation of the particle beam so that the leakage radiation is kept at a management value or less.

Abstract: An inexpensive scanning irradiation device of a particle beam is obtained without using a rotating gantry. A first scanning electromagnet and a second scanning electromagnet, whose deflection surfaces of the particle beam are the same, and which bend the particle beam having an incident beam axis angle of approximately 45 degrees relative to a horizontal direction in reverse directions to each other; an electromagnet rotation driving mechanism which integrates the first and the second scanning electromagnets and rotates these scanning electromagnets around the incident beam axis; and a treatment bed are provided. The particle beam deflected by the first and the second scanning electromagnets can be obtained at a range of ?45 degrees to +45 degrees in deflection angle from an incident beam axis direction.
