Structural composition and classification of X-ray grids

The X-ray machine places an X-ray grid between the film and the human body to reduce the scattered rays received on the film, improve the contrast of the image, improve the imaging quality, and reduce the harm to the human body.
The appearance of the X-ray grid is a 4-8mm thick flat plate. The internal structure is composed of many thin lead strips towards the focal point. The two lead bars are filled and positioned with a material that can easily penetrate X-rays, and then glued together. The filler of the X-ray grid can be wood, cardboard or aluminum. Finally, the top and bottom are sealed with thin aluminum plates to form a grid plate. Viewed from the cross section, the direction of the lead strips of the filter plate will gather to a point.
The X-ray grid is divided into four types according to the structure,
1 Convergent grid: each lead is inclined to the focal point, that is, the extension line of the lead is concentrated on the focal point
2 Parallel grid: each lead is parallel to each other in the vertical plane
3 Cross grid: It is composed of two layers of parallel grids, and the lead bars are at 90° to each other.
4 Arc grid: overlapped with equal radius from the center outwards, tile-shaped
