Why is the X-ray grid better than the larger one

Recently, a customer asked why the X-ray grid is better than a larger grid? Let me explain to you: the larger the grid ratio of the X-ray grid, the higher the grid ratio, the better the effect of eliminating scattered rays. Use a high-grid ratio filter with a large X-ray grid ratio to improve the contrast of X-ray pictures. The commonly used grid ratio is 12:1.
X-ray grid ratio is the ratio of the height of the lead bar to its width
X-ray grid ratio is the ratio of the width of the aluminum bar to its height
X-ray grid grid ratio is the ratio of the lead bar height to its spacing
X-ray grid ratio is the number of aluminum bars per unit distance
The grid ratio of the X-ray grid represents the weight of lead per unit volume.
After reading here, everyone knows why the X-ray grid has a better effect than a larger grid.
