Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] The invention provides a technical solution: a homogenizer structure of an accelerator radiation head that saves treatment space. The homogenizer is divided into two layers. The upper layer is a rotating disk that drives the homogenizer to rotate, and the lower layer is a moving tray that drives the ionization chamber and mirrors to move. The way to increase the treatment space of the radiation head, and at the same time, the entire block can be rotated ...

Abstract

The invention belongs to the technical field of medical accelerators, and particularly relates to an accelerator radiation head flattening filter structure for saving treatment space. The structure comprises a flattening disk rotating component, a flattening filter frame, an ionization chamber and reflector moving component, a flattening disk rotating drive component, an ionization chamber and reflector moving drive component and a limit pin component, wherein the flattening disk rotating component is rotatably mounted at the top of the flattening filter frame through bearings, and the ionization chamber and reflector moving drive component is mounted on the side wall of the flattening filter frame through bolts. A flattening filter is divided into two layers, the upper layer is a rotatingdisk driving a flattening block to rotate, the lower layer is a moving tray driving an ionization chamber and a reflector to move, the size of the flattening filter in the axial direction of a radiation head can be greatly reduced by the two-layer structure, the treatment space of the radiation head is increased, and the diametrical size of the radiation head can be reduced as the flattening block rotates.

Description

technical field [0001] The invention relates to the technical field of medical accelerators, in particular to an accelerator radiation head leveler structure that saves treatment space. Background technique [0002] For the radiation head structure of a conventional medical accelerator, its homogenizer mechanism is divided into three layers, and the homogenizer, ionization chamber and mirror are installed in sequence from top to bottom. For medical accelerators that can simultaneously provide electron beams and X-rays for tumor treatment , the whole block and the electron beam diffuser are usually installed on an eccentric wheel mechanism, and then the ionization chamber and the mirror are installed in order from top to bottom. The structure is also three layers, because the ionization chamber has a certain thickness, and the mirror is based on the actual The requirement of use needs to form a certain angle with the horizontal plane, which leads to a large size in the axial ...
