A homologous double-beam medical accelerator

Abstract

The invention relates to a homologous double-beam medical accelerator, comprising an electron gun, the electron gun is connected with an accelerating tube, the accelerating tube is connected with a coupler, the coupler is connected with a waveguide through a waveguide window, the waveguide is connected with a microwave power source, and the microwave power source is connected with a The modulator, the accelerating tube is provided with three energy switches, the three energy switches are respectively located between the three accelerating cavities in the accelerating tube, each energy switch includes a side coupling cavity and a detuning rod located in the side coupling cavity, and the outlet of the accelerator There is a movable target at the end; the output power of the microwave power source is controlled by the modulator, and the length of the three detuning rods in the side coupling cavity is adjusted at the same time, so as to adjust the energy obtained by the electrons emitted by the electron gun in the accelerating tube, thereby obtaining KeV level X-rays and MeV-level X-rays ensure the coaxiality of imaging and treatment, and improve the healing effect on patients; in addition, the design principle of the present invention is reliable, the structure is simple, and it has a very wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a homologous double-beam medical accelerator and radiotherapy equipment using the accelerator. ), so as to realize the homology and coaxiality of the imaging system and the treatment system during clinical radiotherapy. Background technique [0002] Medical electron linear accelerator is the main equipment of radiotherapy at present, and belongs to an application of low-energy accelerator. According to the level of its output energy, it can be divided into three types: low-energy machine (4-6MeV), medium-energy machine (8-15MeV) and high-energy machine (20-25MeV). [0003] In the process of clinical radiotherapy, positioning is an important link. The current positioning method has large random errors and equipment errors, which weakens the treatment effect, which is mainly caused by the fact that the imaging system and the treatment system belong to different coordinate...
