    • A charged particle irradiation system is capable of shortening the irradiation time and the treatment time by performing efficient irradiation even when irregular variation occurs in the irradiation object during the gating irradiation. The extraction of the beam is stopped upon reception of a regular extraction permission end signal which is outputted based on a regular movement signal. An extractable state maintaining function operates upon the reception of the extraction permission end signal. When a preset standby time elapses without receiving an extraction permission start signal again during the standby time, the extractable state maintaining function finishes its operation and a charged particle beam generator decelerates the beam. Also, the extraction of the beam is stopped due to reception of an irregular extraction permission end signal during the irradiation. When the extraction permission start signal is received again during the standby time, the extraction of the beam is restarted.
    • 带电粒子照射系统即使在门控照射期间在照射物体中发生不规则变化,也能够通过高效照射缩短照射时间和处理时间。 在接收到基于规则移动信号输出的常规提取许可结束信号时,停止提取光束。 可提取状态维持功能在接收到提取许可结束信号时进行操作。 当在待机时间期间经过预设待机时间而不再接收到提取许可开始信号时,可提取状态维持功能完成其操作,并且带电粒子束发生器使光束减速。 此外,由于在照射期间接收到不规则的提取许可结束信号,停止提取光束。 当在待机时间期间再次接收到提取许可开始信号时,重新开始提取光束。
