Abstract

The invention relates to the technical field of proton intensity-modulated radiation therapy, in particular to a dynamic mechanism and device for proton intensity-modulated radiation therapy and a use method. The dynamic mechanism for proton intensity-modulated radiation therapy comprises a stop block assembly and a driving assembly, wherein the stop block assembly comprises a plurality of stop block bodies, the plurality of stop block bodies are connected in a sliding manner, the driving assembly comprises a controller and a driving structure, and the controller is configured to adjust the driving structure, so that the driving structure can drive the stop block bodies to move in a first direction to change the range of a proton beam and the intensity of the proton beam. Through the structure, the scanning time of proton therapy is greatly shortened while the proton therapy is combined with the flash radiation therapy, so that the radiation therapy gain ratio can be increased to the maximum extent, and the contribution to the radiation therapy is maximized.

Description

technical field [0001] The present disclosure relates to the technical field of proton modulated radiation therapy, in particular to a dynamic mechanism, device and usage method for proton intensity modulated radiation therapy. Background technique [0002] Ideal radiation therapy delivers a lethal dose to tumor cells while minimizing radiation dose to surrounding normal organ components. Compared with photons and electrons, the unique Bragg peak of proton therapy gives it such dosimetric advantages. For the existing proton transmission methods, the pencil beam scanning technology is considered to be able to maximize the dosimetric advantages of proton therapy without losing the beam intensity. The inventors found that the scanning time of the proton pen beam scanning technology is too long, especially the energy conversion time is difficult to meet the flash radiation therapy time specification. Contents of the invention [0003] The present disclosure provides a dynami...
