Classification of X-ray grids

X-ray grid is used to filter out the influence of scattered rays on the film. Used to filter out the influence of scattered rays on the film
Should be placed between the human body and the film, most of the scattered rays can be filtered out, and only a small part of the scattered rays can be leaked.
X-ray grid classification:
According to the structure of the X-ray grid:
1 Convergence grid: each lead bar is inclined to the focus, that is, the extension line of the lead bar is concentrated on the focus
2 Parallel grid: each lead bar is parallel to each other in the vertical plane
3Cross grid: It is composed of two layers of parallel grids, and the lead strips are 90° each other.
4Circular arc grid: It is formed by superimposing the same radius from the center outwards, tile-shaped
According to the material of the X-ray grid:
1 Commonly used grid: The internal spacer is composed of non-metallic materials, such as wood chips, paper chips, plastics and other non-metallic low-density materials;
2 All metal grid: the internal spacer is a metal material: aluminum sheet. It has high strength and good moisture resistance.
