Where can the wire grid be placed

The grid is placed between the body and the film (or flat panel detector). That is, the grid is located directly behind the patient, either inside the chest rack or in the cassette under the flat bed.
The focal length of the wire grid for the chest frame is 1.8 meters, and the focal length of the grid for the photography flat bed is 1 meter. Some customers report that the filter grid is not effective in filtering rays, and the film has streaks. They are told that the distance between the filter grid and the X-ray machine is wrong, and it needs to be taken according to the instructions. The distance between the wire grid in the chest X-ray box and the X-ray machine is 1.8 meters, and the distance between the wire grid in the flat-bed film box is 1 meter from the X-ray machine.
