Focusing x ray grid decentering effect

Focusing x ray grid cutting effect refers to the additional absorption of X-ray with information signal by wire x ray grid lead bar.
The effect of focusing x ray grid decentering on the image is that the grating lead bar cuts the same amount of raw rays, resulting in a uniformly reduced image density. Generally, it is difficult to identify from photos and images, and is mistaken for inadequate X-ray photography conditions.
Elimination method of decentering effect of focusing x ray grid: In the range of x ray grid focal length, the center line of X-ray is perpendicular to the grating, and alignment of the x ray grid center line is as far as possible.
