    • The objective of the present invention is to reduce the effect of the hysteresis of a scanning electromagnet so as to obtain a particle beam therapy system that realizes high-accuracy beam irradiation. There are included an irradiation management apparatus (32) that controls the scanning electromagnet (3), based on target irradiation position coordinates (Pi) of a charged particle beam (1b), and a position monitor (7) that measures measurement position coordinates (Ps) of the charged particle beam (1b). The irradiation management apparatus (32) has a command value creator (25) that outputs a control input (Io (Ir)) to the scanning electromagnet (3), based on the target irradiation position coordinates (Pi) and correction data (Ia) created on the basis of the measurement position coordinates (Ps), measured by the position monitor (7) in the preliminary irradiation in which the excitation pattern of the scanning electromagnet is the same as that of the main irradiation plan, and the target irradiation position coordinates (Pi).
    • 本发明的目的是减少扫描电磁体的滞后效果,以获得实现高精度光束照射的粒子束治疗系统。 包括基于带电粒子束(1b)的目标照射位置坐标(Pi)来控制扫描电磁体(3)的照射管理装置(32)和测量位置坐标( Ps)的带电粒子束(1b)。 照射管理装置(32)具有基于目标照射位置坐标(Pi)和校正数据(Ia)向扫描电磁体(3)输出控制输入(Io(Ir))的指令值生成器(25) 基于由扫描电磁体的激励图案与主照射平面的激励图案相同的预备照射中的位置监视器(7)测量的测量位置坐标(Ps)和目标照射位置 坐标(Pi)。
