An intelligent projection system based on four-dimensional single-source gamma knife

Abstract

The invention provides an intelligent projection system based on a four-dimensional single-source gamma knife. The system comprises a radiotherapy treatment planning system, an intelligent tracking system, an automatic collaborative treatment bed, a robot system, a radiation source, a human-computer interaction system and an integrated control system, the automatic collaborative treatment bed, therobot system, the intelligent tracking system, the radiation source and the human-computer interaction system are all connected with the integrated control system; the robot system is used for carrying out focus tracking and focusing irradiation on a patient bound on the automatic collaborative treatment bed, and the ray therapy beam emitted by a gamma source rod is subjected to non-isocentric intensity modulated and digital instant focus tracking laser focused four-dimensional radiotherapy plan projection through a gamma source rod and a collimator system, so that the focal point obtains several times of the radiation dose of the tissues and organs around the focal point, and the dose outside the target is reduced by a cliff type, the absorption dose of the focal tissues is accurate, thedose distribution is uniform, the focal tissue cells generate a radiation biological effect to occur necrosis, and a radiation treatment effect similar to surgical resection is generated.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy equipment, and in particular relates to an intelligent projection system based on a four-dimensional single-source gamma knife. Background technique [0002] Radiation therapy is one of the main treatments for cancer. The biggest problem of the existing radiotherapy equipment is the low level of intelligence, low cure rate in one treatment, inability to cure primary cancer and multiple metastatic cancers at the same time, small focal dose ratio, and many serious adverse reactions and complications. Now used in clinical radiotherapy equipment: such as medical electron linear accelerator, proton heavy ion accelerator, afterloading therapy machine, X-ray therapy machine, 60 Co treatment machine, 60 Co source stereotactic therapy machine (γ-knife), etc., the core components of the above-mentioned equipment are projection systems, and the common defects in the existing projection systems are: 1....

AI Technical Summary

Problems solved by technology

The biggest problem with existing radiotherapy equipment is the low degree of intelligence, low cure rate in one treatment, and inability to cure primary cancer and multiple metastatic cancers at the same time, low focal dose ratio, and many serious adverse reactions and complications.

Now used in clinical radiotherapy equipment: such as medical electron linear accelerator, proton heavy ion accelerator, afterloading therapy machine, X-ray therapy machine, 60 Co treatment machine, 60 Co source stereotactic therapy machine (γ-knife), etc., the core components of the above-mentioned equipment are projection systems, and the common defects in the existing projection systems are: 1. Large irradiation field, clockwise in a single plane / Rotate the irradiation field counterclockwise and spiral the irradiation field along the longitudinal axis of the body; 2. The dose ratio of the scorched skin is small, the dose of surrounding organs and tissues is high and the damage is serious, the systemic side effects are serious, and there are many serious complications; 3. The degree of intelligence is low and the operation is cumbersome. Moreover, its scope of application and treatment accuracy have certain defects, which affect the popularization of use; 4. The price is very expensive, which also greatly affects the popularization of use; 5. The penumbra of γ-ray external irradiation treatment is large, and the off-target damage is serious Complications occur frequently; therefore, it is necessary to develop an intelligent projection system that does not damage sensitive cells, tissues and organs outside the target
