Abstract
The invention relates to radiation therapy system. The system includes a five-degree-of-freedom O-shaped arm radiation therapy device and a six-degree-of-freedom parallel radiation therapy bed. The five-degree-of-freedom O-shaped arm radiation therapy device includes an O-shaped arm movement mechanism, a linear accelerator device, a radiation dose detection device and a double-X-ray machine image positioning mechanism. The O-shaped arm movement mechanism includes an O-shaped arm, an accelerator displacement device, a rotational displacement device, a turning displacement device, a horizontal transverse displacement device, and a horizontal longitudinal displacement device. The double-X-ray machine image positioning mechanism includes an X-ray transmitter and receiver. The six-degree-of-freedom parallel radiation includes a base assembly, a connecting rod assembly and a bed plate assembly. The radiation therapy system of the invention achieves five-degree-of-freedom control of a radiation therapy process with high control accuracy and stability, and has flexible spatial positions and high positioning accuracy of the radiation therapy bed.
