Why is the wire grid better than the larger one?

Recently, a customer inquired why the filter grid is better than the larger one? Let me explain to you below: the larger the grid ratio of the grid, that is, the higher the grid ratio, the better the effect of eliminating scattered rays. Use a high-grid-ratio filter with a large grid-to-grid ratio to improve the contrast of X-ray photographs. A common grid ratio is 12:1.
The grid ratio is the ratio of the height of the lead bar to its width
The grid ratio is the ratio of the width of the aluminum strip to its height.
The grid ratio of the wire grid is the ratio of the height of the lead bar to its interval
The grid ratio is the number of aluminum bars per unit distance.
Wire Grid Ratio The Grid Ratio represents the weight of lead per unit volume.
After reading this, we all know why the filter grid is better than the larger one.
