摘要：
PROBLEM TO BE SOLVED: To provide a particle beam controller which can shorten the time required for irradiation of a particle beam and a control method thereof.SOLUTION: A particle beam irradiation controller comprises: a respiration synchronization unit S1 which monitors the position of a dynamic body target followed by respiratory movement during irradiation of a beam b of a particle beam an irradiation control unit S2 which previously acquires information on the position of the dynamic body target, outputs a beam emission request signal when it is determined that the dynamic body target enters an irradiation range C1 on the basis of the information on the movement position, and outputs a prediction signal immediately before beam emission when it is determined that the dynamic body target is immediately before entrance C2 to the irradiation range C1 where the beam can be irradiated and a beam emission control unit Ts which controls an accelerator 1 and an emission instrument 2s of an emission beam transport line 2B, switches start/stop of beam emission in synchronization with on/off of the beam emission request signal, and performs control so as to start preparation of emission of the beam b of the emission instrument 2s when receiving the prediction signal immediately before beam emission.COPYRIGHT: (C)2016,JPO&INPIT【課題】粒子線を照射するのに必要な時間を短縮できる粒子線照射制御装置およびその制御方法を提供する。【解決手段】本発明の粒子線照射制御装置は、粒子線のビームbの照射中に呼吸性の移動を伴う動体標的の位置を監視する呼吸同期装置S1と、動体標的の位置の情報を予め取得し、移動位置の情報に基づいて動体標的が、照射領域C1に入ったと判定される場合にはビーム出射要求信号を出力し、ビーム照射可能な照射領域C1に入る直前C2であると判定される場合にはビーム出射直前予測信号を出力する照射制御装置S2と、加速器1と出射ビーム輸送ライン2Bの出射用機器2sを制御し、ビーム出射要求信号のオン/オフに同期してビーム出射の開始/停止に切り替え、ビーム出射直前予測信号を受けた場合、出射用機器2sのビームbの出射の準備を開始する制御を行うビーム出射制御装置Tsとを備える。【選択図】図6
