What problems should be paid attention to when using the grid

We all know some problems about the X ray grid. In the previous article, we also talked about the grid, and we all know some grids more or less, but what problems should we pay attention to during use? Let me introduce it to you today, so that you can learn more about it.
The main function of the grid is to make the image clear by filtering the scattered X-rays. It is used to filter out the influence of scattered rays on the film. It should be placed between the human body and the film, so that most of the scattered rays can be filtered out, and only a small part of the scattered rays will pass through.
In the process of using the grid, the following items should be paid attention to:
1. Avoid inversion of the grid when using the grid;
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 grid photography, the plane of the machine head and the grid should be perpendicular, otherwise the X-rays will be absorbed at an angle to the lead strip;
4. When there are many scattered rays in photography, a grid with a larger grid can be considered;
5. When using the cross grid, the tube shall not be inclined in any direction.

The dimensions of our company’s grids are:
6×8 (15×20cm) is suitable for photosensitive materials with a size of 5*7, and the focal length is 0.7-1.8m optional. 9×11 (23×28cm) is suitable for photosensitive materials with a size of 8*10, and the focal length is 0.7-1.8m optional.
11×13 (28×33cm) Suitable for 10*12 photosensitive materials, focal length 0.7-1.8m optional.
12×15 (3038cm) Suitable for photosensitive materials with a size of 11*14, the focal length is 0.7-1.8m optional.
13×16 (33×40cm) is suitable for photosensitive materials with a size of 12*15, and the focal length is 0.7-1.8m optional.
15×15 (38×38cm) is suitable for photosensitive materials with a size of 14*14, and the focal length is 0.7-1.8m optional.
15×18 (38×46cm) is suitable for photosensitive materials with a size of 14*17, and the focal length is 0.7-1.8m optional.
18×18 (46×46cm) is suitable for photosensitive materials with a size of 17*17, and the focal length is 0.7-1.8m optional.
The grid ratios of the above grid sizes are 8:1, 10:1, 12:1.
Specification:
1 Focal length: the vertical distance from the convergent line of the lead strips to the grid surface, f
2 Grid ratio: It is also a grid ratio, which is the ratio of the height of the lead bar to the gap between the lead bars, R
3 grid density: the number of lead strips within a unit distance, N
