Title:
粒子線治療装置
Document Type and Number:
Japanese Patent JP5508553
Kind Code:
B2
Abstract:
The objective is to eliminate the effect of the hysteresis of a scanning electromagnet and resume high-accuracy beam irradiation from an irradiation position where it has been interrupted, even in the case where emergency-stop processing is performed during therapy. There are provided an irradiation management apparatus (32) that controls a scanning electromagnet (3), and an interlock information inputting device (84) that generates an interlock signal for stopping irradiation of the charged particle beam (1), when a contingency occurs. When irradiation of the charged particle beam (1) is resumed, the irradiation management apparatus (32) performs idle operation in which the scanning electromagnet (3) is controlled, with the charged particle beam (1) unirradiated, from a start step, which is situated prior to a stop step and is different from the initial step in actual irradiation, to the stop step, and then irradiates the charged particle beam (1) from the desired irradiation position coordinates (Pi) corresponding to the stop step.
