How to choose x-ray grid?

Clients consulted Newheek’s x-ray grid for size 18X18.
Our x-ray grid are 5 “X18” – 18 “X18” and have a gridding ratio of 8:1, 10:1 and 12:1.
The x-ray grid is placed between the human body and the film to filter out the effect of scattered rays on the film. At present, the x-ray grid is used for camera racks, cameras, and image intensifiers. It is square on camera racks and cameras, and circular at the input end of image intensifiers. The focal length varies with the position of the x-ray grid.
Customers should make appropriate choices according to their own needs when consulting x-ray grid.
