This invention provides an apparatus for particle beam therapy capable of simultaneously seemingly transmitting a particle beam to a plurality of treating room by time sharing. The apparatus (51) for particle beam therapy of this invention has a beam transmitting system (59) and a therapy management device (95). The beam transmitting system (59) has a beam path changer (16) for changing the beam path so that an electron charged particle beam (81) is transmitted to any one of a plurality of particle beam irradiation devices (58). The therapy management device (95) has a beam path controlling device (18) for generating an emitter control signal (csiga) for controlling the emitter (62) of an accelerator (54), and a beam path changer control signal ( higher control signal (csigb) ) for controlling the beam path changer (16), so that the electron charged particle beam (81) is transmitted to any one of the plurality of particle beam irradiation device (58) in each allocated time while the plurality of particle beam irradiation device (58) are performing the therapeutic operation in a same therapeutic time zone.本發明之目的在提供一種藉由分時技術而可猶如同時地將射束輸送至複數個治療室之粒子射線治療裝置。粒子射線治療裝置(51)的射束輸送系統(59)具有:變更射束路徑以將帶電粒子束(81)輸送至複數個粒子射線照射裝置(58)的任一個之射束路徑變更器(16),治療管理裝置(95)具有射束路徑控制器(18),該射束路徑控制器(18)針對要在同一治療時間帶進行治療之複數個粒子射線照射裝置(58),產生用來控制加速器(54)的射出器(62)之射出器控制訊號(csiga)及控制射束路徑變更器(16)之射束路徑變更器控制訊號(踢出控制訊號(csigb)),以讓帶電粒子束(81)在每分配時間輸送至複數個粒子射線照射裝置(58)的任一個。10‧‧‧踢出電磁鐵12a至12j‧‧‧偏向電磁鐵16‧‧‧射束路徑變更器18‧‧‧射束路徑控制器20‧‧‧主導管21‧‧‧導管分歧部22a、22b‧‧‧下游導管23‧‧‧上游射束輸送系統24a、24b‧‧‧下游射束輸送系統25a、25b‧‧‧治療台26a、26b‧‧‧呼吸訊號產生器27a、27b‧‧‧患者感測器29a、29b‧‧‧治療室30a、30b‧‧‧患者31a、31b‧‧‧照射對象51‧‧‧粒子射線治療裝置52‧‧‧射束產生裝置53‧‧‧線性加速器54‧‧‧圓形加速器(加速器)55a、55b、55c‧‧‧偏向電磁鐵56‧‧‧離子源58a、58b‧‧‧粒子射線照射裝置59‧‧‧射束輸送系統61‧‧‧入射器62‧‧‧射出器88a、88b‧‧‧照射管理裝置120‧‧‧主管理裝置121‧‧‧加速器系統控制裝置csiga‧‧‧射出器控制訊號csigb‧‧‧踢出控制訊號(射束路徑變更器控制訊號)psig1、psig2‧‧‧呼吸訊號
