I. More reliable: The treatment plan is automatically transmitted to the operating table, which is also digitally connected to the automatic positioning system. Second, more effective: the use of accurate automatic positioning system shortens the treatment time, avoids human error and significantly improves the cure rate. Third, more secure: the use of accurate protection, protection devices and independent multiple detection and verification system. Fourth, more accurate: 201 beams of gamma rays are statically geometrically focused with a focusing accuracy of 0.1mm. Fifth, more automatic: Fully automatic equipment switching device expands the range of indications, protects important nerve structures and meets the need to treat lesions of different shapes. VI. More perfect: The 3D treatment planning system can be networked with various diagnostic imaging devices to directly acquire 3D digital positioning images, perform fusion of various images, automatically set up target points, and automatically optimize treatment plans. VII. More options: Multiple treatment plans can be implemented, and the repetitive fixator implements split treatment or split treatment for tumors, which greatly improves the treatment effect.
