What is the role of X-ray grid

The X-ray grid is a device that allows the original emission lines to pass through and filters out scattered rays to improve image quality. Among them, the definition of the original emission line and the secondary ray are the original emission line and the primary ray and the ray emitted from the X-ray tube, the scattered line 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 generated rays have a wavelength longer than the original emission line and the radiation direction is scattered and irregular.
The X-ray grid should be standardized when used, otherwise it will not be able to filter out the scattered rays, and will not achieve the purpose of use. The X-ray grid is divided into two sides, the front side is the focusing surface, and the focusing surface and the focusing surface are literally understood as the side facing the focal point of the X-ray tube, that is, the side with the convergence line.
