What should we know about the grid?

The main function of the grid is to filter out the scattered lines. The scattered rays are caused by a special effect of a part of the X-rays passing through the human body, so that the original X-rays change the direction of propagation, and the rays having different propagation directions are called scattered lines.

When the grid is used, it should be standardized or it will not be able to filter out the scattered lines, which will not be used. The grid is divided into two sides, the front side is the focal plane, the focal plane and the focal plane are literally facing the side of the X-ray tube focus, that is, the side of the convergence line.
