X-ray grid

The X-ray grid is mainly used to filter out the influence of scattered rays on the film or image. Most scattered rays are filtered out, and only a few direct rays pass through. Therefore, the diagnostic quality of the image by the medical device is improved, and a clearer and more accurate x-ray image is provided.

The appearance of the X-ray grid is a 4 to 8 mm thick plate. The internal structure consists of many focused thin lead strips. The two lead strips are filled with a substance that easily passes through x-rays and sticks together. The filler can be wood, paper or aluminum. Finally, use a thin aluminum sheet or carbon fiber board to form a grid board. From the cross section, the layout direction of the filter plate leads will converge to one point. From the entire lead plate, there is a convergence line.

X-ray grids are classified according to their structure. 1. Convergent grid: Each lead is inclined to the focal point, that is, the extension of the lead is concentrated on the focal point. 2. Parallel grid: each lead is parallel to each other on the vertical plane. 3. Cross grid: It is composed of two parallel grids, the lead direction is 90 °. 4. Arc-shaped grid: expand outwards from the center, overlapping with equal radius, like tiles.

If you also have the need for grids, please inquire and discuss cooperation. People from all walks of life are welcome to inquire and discuss related matters such as supporting production, maintenance and replacement, and agency trade.
