What size X-ray grid is used for normal chest radiographs

Some customers have inquired about the size of the X-ray grid for normal chest radiographs. Generally speaking, for chest radiographs, film or flat-panel detectors are 17X17 inches and 14X17 inches, which are common sizes for normal chest radiographs. The corresponding X-ray grid size is 18X18 inches and 15X18 inches.
The X-ray grid is mainly used to filter out the influence of scattered X-rays on the film and the plate. It should be placed between the human body and the film or the plate. Most of the scattered rays can be filtered out, and only a small part of the scattered rays leaks. . The X-ray grid can improve the filming quality of X-ray machines, and the X-ray grid can filter scattered rays, reduce fog and improve contrast. Therefore, the X-ray grid can improve the quality of the film when the thickness and density of the object being photographed are relatively large. It is recommended to use X-ray grids for filming with high-frequency X-ray machines, and the effect will be better.
