Multi-source focusing therapy and conformal intensity-modulating therapeutic radiotherapy equipment and collimator combination thereof

Abstract

The invention relates to multi-source focusing therapy and conformal intensity-modulating therapeutic radiotherapy equipment which comprises a base, an exercise bed, a roller, a treatment head and a counterweight. The treatment head includes a shielding body, a radiation source which is arranged in the shielding body and is used for focusing treatment, a source carrier body for conformal treatment, a switch body for controlling a source body to be switched on and switched off, a radiation ray shielding door that shields the radiation source in a controlled mode, and a collimator combination. By using the multi-source focusing therapy and conformal intensity-modulating therapeutic radiotherapy equipment provided by the invention, the problem that stereotactic multi-source focusing treatmentand conformal intensity-modulating treatment cannot be realized in the same piece of equipment at present is solved. The present invention also provides the collimator combination.

Description

technical field [0001] The invention relates to the technical field of large-scale medical equipment, in particular to a radiotherapy equipment for multi-source focus therapy and conformal intensity-modulated therapy and a collimator combination thereof. Background technique [0002] Tumor is a common frequently-occurring disease, and radiation therapy is a common treatment. Stereotactic gamma ray whole body therapy system (hereinafter referred to as Gamma Knife) is a kind of radiotherapy equipment. In the process of Gamma Knife radiotherapy, there are generally two radiotherapy methods, stereotactic multi-source focused therapy radiotherapy and conformal intensity modulation Treatment with radiotherapy. The so-called stereotactic multi-source focused radiotherapy method is to emit gamma rays into the body, focus during the emission transmission process, and focus on a point, and form a high-energy treatment point through the conversion of sound waves and heat energy at thi...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no gamma-ray stereotactic radiotherapy equipment that can integrate stereotactic multi-source focused therapy radiotherapy and conformal intensity-modulated radiotherapy. In other words, the current Gamma Knife equipment cannot It can realize both precise treatment and conformal intensity-modulated therapy. For patients, it is also impossible to choose different treatment methods for different tumors on the same device.
