Motion Management with Respiration Guidance Gating System Verified Firstly on the Heavy-ion Therapy Facility in Lanzhou

HIMM装置上首次验证呼吸引导门控系统

In order to treat the moving targets under the synchrotron-based pulsed heavy-ion beam delivery,a novel respi-ration guidance gating system(RG2S)was developed to synchronize the patterns between the patients'respiration and synchrotron magnetic excitation curve(MEC)^([1-3]).
