The effect of grid focal length difference

The difference in grid focal length affects the image capture effect. –The general grid is installed on the filming frame and filming bed to filter the stray scattered rays, making the image clearer and reducing 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 upright and supine shooting, a 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.
Huarui Imaging provides filter grids with conventional parameters, if necessary, please call for consultation.
