What is the difference between a wire grid and a wire filter, and how should I choose?

We know that X-ray examination is a very important item in medical imaging examination, but in X-ray examination, scattered rays will inevitably appear, which will interfere with the final imaging, so how to obtain a clear image, this is pursued by many researchers.
The grid is an important component to obtain clear images. So what is the difference between the grid and the filter we usually say?
The grid is an important part of the filter. The grid with low grid density will have shadows when it is used, so it should be used as an active grid. This is where the filter comes in.
But now the fixed grid has a high grid density, so its shadow can be basically ignored, so now a fixed grid is generally used.
