Problems solved by technology

[0004] In addition, the existing linear accelerator also has an electron therapy mode in addition to the photon therapy mode. Therefore, a homogenizer suitable for homogenizing photons is not suitable for electron therapy.
Also, typically, the electron therapy mode does not have a straightener and allows the electrons to pass directly through the collimator

Embodiment Construction

[0036] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 as shown, figure 1A perspective view of a collimator positioning assembly 100 according to one embodiment of the present invention is shown. The collimator positioning assembly 100 is fixed on the substrate 200, and the collimator positioning assembly 100 includes: a controller (not shown), a driver 102, an encoder 104, a disc-shaped carrier 106, a switch assembly 108 and a locking assembly 110 . Specifically, the disc-shaped carrier 106 is divided into upper and lower parts, and the upper part is a disc-shaped carrier main body 106a. The central portion of the disc-shaped carrier body 106a is provided with a central through hole, around which seven positioning holes are evenly arranged, each positioning hole is ...

Abstract

The invention discloses a collimator positioning component; the collimator positioning component is fixed on a substrate; the collimator positioning component comprises a driver; a carrier driven by the driver, wherein the carrier is defined with at least two collimating devices capable of aligning to a beam, and the carrier is further defined with at least grooves with corresponding collimating positions and approximately V-shaped sections respectively; a locking component, which comprises a sleeve fixed on the substrate, an elastic piece arranged in the sleeve, and an actuating device pressed by the elastic piece, exposed from the inner part of the sleeve part and leaned on the carrier; when one of at least two collimating positions of the carrier is aligned to the beam, the actuating device of the locking component is pressed to the groove corresponding to the collimating device by the elastic piece.

Description

technical field [0001] The present invention relates to the field of medical equipment, specifically to the field of medical linear accelerators, and more specifically to a collimator positioning assembly and a positioning method used on medical linear accelerators. Background technique [0002] Accelerating tubes In medical linear accelerators, the X-rays used to treat patients need a certain degree of uniformity within the radiation field range. Uneven X-rays will increase the skin dose and cause harm to patients. However, the energy distribution of the X-rays actually produced by the medical linear accelerator is not uniform, but concentrated in a small angle range in the incident direction, which does not meet the clinical requirements for the energy distribution of the rays. Therefore, in the linear accelerator, a homogenizer is used to homogenize the generated X-rays. [0003] X-rays with different energies correspond to equalizers with different shapes. For medium-e...
