How to choose the right x-ray grid? What are the precautions

Are you curious how to choose the right x-ray grid? What are the precautions, the following small series will talk about.
The X-ray grid is a flat plate used to filter scattered rays. Due to its participation, the images obtained after X-rays are irradiated will be clearer. So how do we choose the right X-ray grid? Mainly in terms of size, grid density, grid ratio and focal length: 1. Size: from 8*10 to 17*17, choose according to specific needs; 2. Grid density: the number of x-ray grids formed by lead strips and its spacing per unit length. In special cases, high-density x-ray grids are required, which can be selected according to the specific needs of customers; 3. Grid ratio: the ratio of lead bar height to lead bar gap, commonly used 6:1, 8:1, 10:1 , 12:1, etc., the larger the ratio, the better the effect of absorbing and scattering your rays, which is selected according to the specific needs of the customer; 4. Focal length: the vertical distance from the convergence line of the lead strip to the grid plate. Commonly used focal lengths are 1m, 1.3m, 1.5m and 1.8m, which can be selected according to chest radiographs or other parts.
