Precautions for the use of grids in x-ray photography

When we usually use the grid, we must pay attention to the front of the grid facing the X-ray tube. At this time, someone has to ask, how to distinguish the front and back of the grid? In fact, it is very simple, the front of the grid is labeled, and there is a center line of the grid. Now you don’t have to worry that the grid will be reversed.
In addition, please note that wooden boxes must be used during transportation. In normal storage, you must ensure that it is placed horizontally or vertically.
When we take chest radiographs, we should pay attention to the grid with a focal length of 1.8m, and when we take pictures in bed, we need to match a grid with 1m.
