What are the filter grids?

What kind of grids are there? Do you know? Let me tell you about
The X-ray grid is a device that passes the original emission line and filters out the scattered light to improve the image quality. Among them, the definition of the original emission line and the secondary ray is the original emission line and the primary ray and the ray emitted from the X-ray tube, the scattered ray and the secondary ray and the original emission line are injected into the human body and have a special effect on the human tissue. The resulting rays have longer wavelengths than the original emission lines, and the radiation directions are scattered and irregular.
The X-ray filter grid should be standardized when used, otherwise it will not be able to filter out scattered rays and will not achieve the purpose of use. The X-ray filter grid is divided into two sides, the front side is the focusing plane, the focusing plane and the focal plane are literally the side facing the focal point of the X-ray tube, that is, the side with the convergence line.
In fact, there are many types of X-ray grids, which can be divided into the following categories according to their structure, material and movement mode. According to its structure, it can be divided into three types: convergent grid, parallel grid and cross grid. According to its material classification, it can be divided into metal and non-metal, and can be divided into fixed type and movable type according to its movement mode.
