What is the effect of the difference in focal length of the grid?

The difference in grid focal length affects the image capture effect. Generally, the wire grid is installed on the film frame and the film bed to filter the stray scattered rays, make the image clearer and reduce the radiation to the human body. Usually, it is mainly used to take chest X-rays when it is installed on a filming frame. At this time, a filter grid with a focal length of 1.8 meters should be selected. When installed on a film bed, a filter grid with a focal length of 1 meter should be selected. When a wire grid is required for both vertical and horizontal shooting, a wire grid with a focal length of 1.3 meters should be selected. If the selection of the focal length of the grid is wrong, it will result in uneven images, which will affect the doctor’s diagnosis.
