Abstract

The present invention relates to the technical field of medical devices. Disclosed is an adjustable collimator, which can solve the problem that existing collimators cannot achieve precise therapy in a small irradiation field. The adjustable collimator comprises a controller and two blade sets arranged opposite to each other; the blade sets comprise a plurality of blades, the controller drives the blades to move so as to form a first irradiation field through which a ray can pass; at least one blade in the blade set is a small irradiation field blade, and at least one irradiation field hole is provided on the small irradiation field blade; the controller is further used to drive the small irradiation field blade to move such that the irradiation field hole becomes a second irradiation field through which the ray can pass, wherein the second irradiation field is smaller than the first irradiation field. The technical solutions of the present invention may achieve precise therapy on diseased parts, improving the therapeutic effect of radiotherapy.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable collimator, a collimation system, a treatment head and radiotherapy equipment. Background technique [0002] Existing radiation therapy equipment usually uses multi-source focusing to treat diseased parts. However, due to the different position, size and treatment accuracy requirements of different diseased parts, collimators of different specifications need to be replaced frequently to adjust the beam beam. Diameter size and shape form focus targets with different focus sizes to meet the shape, size and radiation dose required for treatment when the rays pass through the focus target. However, due to the structural limitations of existing radiotherapy equipment and collimators, there are fewer types of collimators, and the beam formed by the radiation has a single shape and a larger field, which cannot meet the accuracy requirements for small field treatmen...
