X-ray grid placement position

The X-ray grid is placed between the human body and imaging equipment (such as flat panel detectors or films). In other words, the X-ray grid is placed directly behind the patient, installed in the bucky stand film box or in the film box under the photographic flat bed.
The focal length of the X-ray grid for bucky stand is 1.8 meters, and the focal length of the X-ray grid for photography flat bed is one meter. Therefore, the distance between the X-ray grid and the X-ray machine depends on the actual situation. The X-ray grid in the bucky stand box is one meter eight meters away from the X-ray machine. The X-ray filter in the medical X-ray table box The wire grid is one meter away from the X-ray machine.
Some customers reported that the X-ray grid was not effective in filtering radiation, and the film was not clear. They informed that the distance between the X-ray grid and the X-ray machine was incorrect, and they needed to follow the instructions. After the customer adjusted the distance, the image was very clear.
