Beam splitting application system for medical electron linear accelerator

The invention relates to a beam splitting application system for a medical electron linear accelerator. The beam splitting application system is composed of an accelerator equipment machine room, the medical electron linear accelerator, a plurality of rotating racks for utilizing deflection magnets, a focusing element for guiding and controlling beam motion, a transfer line, deflection magnets, treatment rooms, a treatment couch and a control system. The medical electron linear accelerator and the rotating racks for controlling the beam motion are respectively mounted in the equipment machine room and the treatment rooms, and the medical electron linear accelerator is used for concentrating beam outlet lines and conveying to the treatment rooms. A doctor can carry out radiation therapy by turning on a beam electric control switch according to the beam types required by patients, so that the common problem that the rotating racks for controlling the beam motion are overweight to influence the isocenter accuracy is thoroughly solved, the manufacturing requirement of the rotating rack components and the purchase cost and maintenance cost of the equipment are reduced, and the problem that the quality requirement of maintenance personnel is high is solved. Positioning and treatment are carried out in different treatment rooms at the same time, and thus the treatment efficiency of single accelerator is improved.
