<p><P>PROBLEM TO BE SOLVED: To provide a charged particle beam irradiation device capable of suppressing the decline of irradiation accuracy due to a rotation angle or a swing angle of a trestle without enlarging the trestle, and suppressing the decline of the irradiation accuracy in a scanning system. <P>SOLUTION: The charged particle beam irradiation device 1 for irradiating a body to be irradiated with a charged particle beam R includes: an irradiation nozzle 6 which has a scanning magnet for scanning the charged particle beam R and irradiates the body to be irradiated with the scanned charged particle beam R; a deflection magnet 5A which deflects the charged particle beam R sent from a cyclotron 2 to the irradiation nozzle 6; a rotating gantry 3 where the irradiation nozzle 6 and the deflection magnet 5A are arranged, and which is rotatable with a rotation axis P as a center; a position detection part 8 which detects positional relation between the rotation axis P and an irradiation position of the charged particle beam R radiated from the irradiation nozzle 6; and a controller T which adjusts the irradiation position of the charged particle beam radiated from the irradiation nozzle 6 by utilizing a detection result of the position detection part 8 corresponding to the rotation angle of the rotating gantry 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
