Multi-source focused therapy and conformal intensity-modulated therapy radiotherapy equipment and collimator combination

Abstract

The invention relates to a radiotherapy equipment for multi-source focus therapy and conformal intensity-modulated therapy, which comprises a base, an exercise bed, a roller, a treatment head and a counterweight. The treatment head includes a shielding body, a source body that is accommodated in the shielding body and is provided with a radiation source for focused therapy and a radiation source for conformal therapy, a switch body for controlling the switch of the source body, and a Radiation ray shielding door and collimator combination for ground-controlled shielding of radioactive sources. The radiotherapy equipment for multi-source focused therapy and conformal intensity-modulated therapy provided by the present invention is used to solve the problem that stereotactic multi-source focused therapy and conformal intensity-modulated therapy cannot be realized on the same device at present. . The invention also provides a 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.
