Abstract

A conformal radiotherapy device, comprising: a synchronous transmission device 2 mounted on a radiation protection assembly 4, a beam switching device, and a source carrier assembly connected to the shaft of the synchronous transmission device 2, and the synchronous transmission device 2 , the beam limiter assembly connected to the axis of the beam switching device 1 . The advantage is that the radiation dose is concentrated in the tumor area (focus) due to the three-dimensional focus formed by the rotation of the radiation beam, and the damage to normal tissues is small. The dose distribution at the tumor can be adjusted by controlling the starting angle and ending angle of the radiation beam irradiating the tumor. The purpose of conformity is achieved by continuously superimposing the irradiation fields of different dose distribution forms. By changing the incident angle of the spatial concentration of the ray beam, it can significantly reduce the damage to the normal tissue when the target spot meets; by automatically controlling the closing of the ray beam, the sensitive organs of the patient will not be damaged.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a conformal radiotherapy device. Background technique [0002] Radiation therapy is one of the important means to treat tumors, clinically 60-75% of tumor patients need radiation therapy. Currently, there are two main categories of methods used in radiation therapy: [0003] 1. Conventional radiation therapy: such as cobalt 60 therapy machine and medical X-ray accelerator. In conventional radiotherapy, a few irradiation fields with different incident angles are generally used to irradiate the planar focusing technique. [0004] 2. Conformal radiation therapy: This technology is the mainstream technology of tumor radiation therapy in the 21st century. Its important feature is to make the distribution of high dose consistent with the shape of the tumor in the three-dimensional direction. That is, the radiation dose is concentrated on the tumor, and the dose to surrounding normal...
