Key Features and Benefits


1. Built-in automatic multi-leaf grating, the maximum field size is 40cmX40cm, the two blade group box (equal projection) can reach 20cm, the blade passing beam center distance is 15.5cm, and the size of the current similar products is the largest.
2.60 pairs of grating blades, the most suitable shape in the current products:
3. Three kinds of blade width: 84 pieces 0.5cm, 32 pieces 1.0cm, 4 pieces 1.5cm:
4. The surface of the blade is specially hardened, the wear resistance is high, the processing and assembly precision is very high, reaching about 0.01mm
5. The internal layout is reasonable, the control system has high integration, and the operation is stable and reliable.
6. Each blade except the motor device is controlled by an encoder, and the self-developed multi-head potential (patented product) is applied to feedback the actual position of the blade, and the blade box realizes closed-loop control with a grating ruler: each control motor The core controller adopts advanced PID control algorithm to control the position and speed of the motor, and the control software adopts redundant algorithm and safety protection control method to greatly improve the safety and reliability of the whole system.
7. The system operation software is integrated with the operating system of the accelerator, and a set of operating system is shared to realize the linkage control of the multi-leaf collimator and the accelerator, which greatly reduces the operation difficulty of the clinician.
8. Advanced TPS System
9. Integrating international advanced 3D CT simulation and comprehensive radiotherapy planning functions, providing a complete and advanced solution for the current linear accelerator conformal intensity modulated external irradiation treatment
