Embodiment Construction

[0052] In practical applications, there is a certain relationship between the size of the penumbra generated during irradiation and the shape of the end surface of the end face of the collimator blade that is close to the other array opposite to the array where the blade is located. One end of the other array opposite to the array where the vanes are located serves as the first end of the vanes.

[0053] At present, the shape of the end face of the first end of the blade is usually set to the following two types:

[0054]The first one, referring to Chinese Patent Application No. 201220426615.7, is to set the shape of the end face of the first end of the blade as a straight end face. Since the curvature at the linear end surface is 0, and the curvature of the two ends of the blade in contact with the linear end surface is larger, therefore, along with the linear motion of the blade, when the radiation generated by the radiation source passes through the linear end surface of th...

Abstract

The invention provides a collimator, a radiation system and a collimator blade selection method. The collimator comprises two or more blades, the blades are arranged oppositely in two arrays, and each of the arrays comprises more than one blade; the blade comprises an extension structure, and the extension structure comprises a first end and a second end oppositely arranged in the extending direction, wherein the end surface of the first end is in the shape of a first curve. By setting the shape of the end face of the first end of the collimator blade as the first curve, the half-shadow change can be made more uniform so as to make the first curve-shaped collimator more conducive to radiotherapy.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on May 28, 2014 with the application number 201410231053.4 and the title of the invention "collimator, radiation system and method for selecting collimator blades". technical field [0002] The invention relates to the technical field of medical equipment, in particular to a collimator, a radiation system and a method for selecting collimator blades. Background technique [0003] A collimator is a medical device used to generate a conformal radiation field, that is, to limit the range of therapeutic rays generated by a radioactive source on the patient's body surface, thereby protecting the patient's normal organs or tissues from radiation. Collimators have a wide range of applications in the field of radiation therapy. [0004] A collimator typically includes a plurality of leaves arranged in two arrays, forming pairs of opposing leaves. Each blade of a ...
