Extrahigh energy electron beam or photon beam radiotherapy robot system

Abstract

The invention provides an extrahigh energy electron beam or photon beam radiotherapy robot system which comprises a laser driving system, a laser plasma accelerator, an electron beam focusing system, a photon beam aiming system, a robot body and a laser beam stabilization system. The laser driving system generates and spreads intense laser pulses to the laser plasma accelerator installed at the tail end of the robot body, and therefore electron beams are generated; the electron beam focusing system guides the electron beams to diseased parts of a patient; the photon beam aiming system enables the electron beams to generate high energy photon beams so that extrahigh energy electron beam radiotherapy or photon beam radiotherapy can be performed; the robot body spreads the electron beams or the photon beams to the diseased parts of the patient in multiple directions; the laser beam stabilization system monitors the positions of laser beams and corrects errors. The extrahigh energy electron beam or photon beam radiotherapy robot system is more compact, more efficient, cheaper and easier to operate and has higher performance than an external irradiation radiation therapy system in the prior art.

Description

technical field [0001] The invention relates to a robot system for external radiation therapy in the technical field of novel medical equipment, in particular to a robot system for radiation therapy using ultra-high-energy electron beams or photon beams. Background technique [0002] Radiation therapy uses high-energy radiation such as X-rays, gamma rays, electrons, protons, heavy ions, and neutrons to kill cancer cells by damaging their DNA. Because radiation therapy damages normal cells while killing cancer cells, treatment must be carefully planned to minimize this side effect. Radiation used for cancer treatment can come from a device outside the body, known as external beam radiation therapy, or from radioactive material implanted in the body near cancer cells, known as internal beam radiation therapy or brachytherapy. External beam radiation therapy usually uses beams of photons (X-rays or gamma rays). The dose of electron beam drops rapidly after a limited distance,...

Problems solved by technology

Therefore, the construction and operation costs of such facilities are unbelievably large, which makes it difficult for conventional accelerator-based ultra-high-energy electron beam radiotherapy systems to be popularized in small-scale hospitals

Although Document 3 discloses an ultra-high-energy electron beam radiotherapy system using a more compact LINAC accelerator and a gantry-type turntable, its principle is still based on a linear accelerator, so it cannot be made more compact in structure
