Multi-leaf collimator device

Abstract

The invention discloses a multi-leaf collimator device, which comprises at least two groups of box bodies, wherein the two groups of the box bodies are arranged in a layered manner, each group of thebox bodies comprises a first sub-box body and a second sub-box body, the first sub-box body and the second sub-box body are symmetrically distributed; each group of the box bodies comprises a plurality of blade driving structures, each blade driving structure comprises a driving device, a blade and a connecting device, the driving device is connected with the connecting device and is used for driving the connecting device to move, and the connecting device is connected with the blade and is used for driving the blade to move to a target position when the driving device works. According to thetechnical scheme of the embodiment of the invention, the technical problem that the slow moving of the blade causes the prolonged radiation field adjusting time so as to reduce the user experience inthe prior art is solved, and the technical effects of the blade moving speed is increased and the blade adjusting time is reduced so as to improve the user experience are achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical technology, and in particular to a multi-leaf collimator device. Background technique [0002] In the prior art, the multi-leaf collimator is widely used in radiotherapy systems, and is used to provide radiation fields of the radiotherapy system. However, at present, each leaf in the multi-leaf collimator moves slowly to the target position, which increases the formation time of the radiation field required in the radiotherapy plan, makes the treatment time of the patient longer, and the radiation dose received increases. Contents of the invention [0003] An embodiment of the present invention provides a multi-leaf collimator device, so as to realize the technical effect of increasing the moving speed of the blades, reducing the adjustment time of the blades, and improving user experience. [0004] An embodiment of the present invention provides a multi-leaf collimator device, whic...
