Chengdu customer consultation x ray grid parameters

The appearance of the x ray grid is a flat plate with a thickness of 4 ~ 8MM. The internal structure is made of many thin lead bars arranged in focus. The two lead bars are filled with X-ray transparent material for positioning, and are bonded together. The filler can be wood, paper or aluminum sheet. Finally, the top and bottom are encapsulated with a thin aluminum plate or carbon fiber panel to form a filter grid. Seen from the cross section, the arrangement direction of the lead strips of the filter plate will converge to a little. From the whole grid, there is a convergence line

Parameter:
1. Focal length: the vertical distance from the lead convergence line to the grid surface, F
2. Grid ratio: also called grid ratio, which is the ratio of lead bar height to lead bar gap, R
3. Grid density: the number of lead bars per unit distance, N
