A gamma-ray therapeutic system applied to treatment of body tumors 1 first-author 1 1 1 1 State Engineering Research Center of Numerical Control System, Mechanic Science and Engineering College, Huazhong University of Science and Technology, Wuhan 430074 State Engineering Research Center of Numerical Control System, Mechanic Science and Engineering College, Huazhong University of Science and Technology, Wuhan 430074 In order to treat malignant tumors in human body, a stereotactic gamma-ray whole-body therapeutic system has been developed. This system is a typical large mechatronics treatment machine. in this paper, its main working principles and characteristics are introduced. This system comprises a special gallows frame with an open vertical structure, a changeable collimator device by which the size of convergence center can be chosen, and a 3D treatment couch. A computer brings the couch to target position automatically. Therefore precise and dynamic rotary converging therapy for tumors located anywhere in the body has been realized. The system's performance has been proved in practice, which includes good curative effect, reliable automation, and safe and secure operation.
