1518 grid is divided into focal plane and back focal plane

The 1518 wire grid is a regular size x ray gridfor X-ray machines, which can be installed on a photographic flat bed and a photographic frame. The function of the wire grid is to eliminate the stray scattered rays to make the image clearer and reduce the radiation amount of the rays to the surrounding people.
The focusing surface of the filter grid is the side facing the tube of the X-ray machine. Generally speaking, the focusing surface of the filter grid will be labeled. Special attention should be paid during installation. If the installation is wrong, it will seriously affect the use effect of the filter grid and the shooting. image quality.
The specifications of the X-ray filter grid mainly include size, grid density, grid ratio, and focal length. Regarding the size of the X-ray filter grid, the selection mainly refers to the size of the imaging cassette or flat panel detector. For a 17-inch imaging plate, choose an 18*18-inch X-ray grid. The grid has three parameters of 12:1, 10:1 and 8:1 than the regular specification. Regarding the focal length, we recommend choosing an X-ray filter grid with a focal length of 1.8 meters if shooting upright chest X-rays, and an X-ray grid with a focal length of 1 meter when shooting the lumbar spine in a supine position.
