Embodiment Construction

[0015] Figure 1, Figure 2, image 3 As shown, the collimator 1 of the present invention is a convex flat plate structure. On the same straight line above the small end of the collimator 1, there are centerlines that are uniformly distributed to both sides, facing the large end below, focusing The 22 focusing collimation holes 2 distributed in a fan shape at one point are arranged in a single row. Positioning holes 4 are respectively opened on both sides of the large end surface of the collimator 1. A rectangular slot 5 perpendicular to the large end face, and a square through hole 6 perpendicular to the large end face is opened in the rectangular slot 5 .

[0016] The angle between the centerlines of the 22 focusing collimation holes 2 is 50°. The large end surface of the collimator 1 is provided with a central keyway 3 .

[0017] like Figure 4 As shown, when the collimator 1 needs to be installed into the reference groove 13 of the outer shield block 12, the central keyway...

Abstract

The invention is convex tabulate collimator, on the small end of which, 22 focalize collimate holes are distributed in sector shape. On the two sides of the big end, the locating holes are set respectively. At the bottom of the collimator, the rectangular slot is opened perpendicular to the big end. The included angle of the centerline of the 22 focalize collimate holes is 50 Deg. The collimator of lighter weight and smaller bulk is convenient to be applied in the medical equipment.

Description

Technical field [0001] The invention relates to a radiation device, in particular to a plate collimator of radiotherapy equipment. Background technique [0002] The collimators used in the existing Gamma Knife are all hemispherical, barrel-shaped, block-shaped structures, large in size and heavy in weight. There are few types of collimators. It is not possible to add collimator types after leaving the factory. It is difficult to meet the requirements of conformal radiotherapy. Contents of the invention [0003] The object of the present invention is to provide a plate collimator of radiotherapy equipment, which is adapted to the radiation device of the radiotherapy equipment developed by the applicant for automatic and rapid exchange with the used collimator and addition in the collimator library. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: the collimator is a convex flat plate structure, and on the same stra...
