Why is X-ray grid not used for DR chest radiographs?

I believe that many people have taken chest radiographs when they are sick, and many physical examination items also include chest radiographs as routine examination items. In the early days, hospitals used industrial frequency X-ray machines, most of which were used with X-ray grids. A careful friend discovered that the X-ray grid is not used for chest radiographs with DR in many hospitals. Why is this?
In fact, whether or not the X-ray grid is used is mainly related to the machine. The main function of the X-ray grid is to filter out the scattered scattered rays. The early power frequency X-ray machines produced a lot of stray scattered rays due to the relationship between bands and frequencies. If the stray scattered rays are not filtered by the X-ray grid, the chest radiograph will be unclear, leading to misdiagnosis or inadequate diagnosis, etc. problem. However, current DR machines use high-voltage generators, and high-frequency X-ray machines produce less spurious scattered rays. In addition, the DR system generally has a grid function, so many DR chest radiographs are not used. X-ray grid.
