What is a x-ray grid

Thex-ray grid is a device placed in front of the film frame to absorb and filter the scattered rays irradiated on the chest frame, thereby improving the contrast of X-ray images.
The x-ray grid is made up of X-ray absorbing lead and penetrable X-ray material in a certain format.
The orientation of the vertical axis of the lead bar in the x-ray grid is the grid shape of the x-ray grid.
Linear x-ray grid can be divided into parallel grids and focusing grids if they are geometrically classified, and static grids and movable grids if they are structurally classified.
At present, static or active linear focusing x-ray grid is used in clinic.
