Precautions for using grid

The main function of the grid is to make the image clear by filtering the scattered X-rays. In the process of using the grid, you need to pay attention to the following matters:
1. When using the grid, avoid the grid inverted;
2. The center line should be aligned with the center line of the grid, and the left and right deviation should not exceed 3cm;
3. When using the grid for photography, when the X-ray tube needs to be tilted, the tilt direction must be consistent with the direction of the lead strip, otherwise the X-ray and the lead strip will form an angle and be absorbed in a large amount;
4. When there are a lot of scattered rays in photography, you can consider choosing a wire grid with a larger grid;
5. When using a cross-type grid, the X-ray tube must not be tilted in any direction.
