Under what circumstances can the film quality of X-ray machine medical equipment be improved by using X ray grid ? The function of theX ray grid is to filter the scattered rays, reduce the haze and improve the contrast. When the thickness and density of the object being photographed is large, the quality of the film can be improved by using the X ray grid . If you use a high-frequency machine, you will get better results. What are the important specification parameters of X ray grid ? What role do the parameters of X ray grid play in it?
The main specifications of X ray grid are grid density, grating ratio and focal length. Grid density: the number of lead bars arranged per unit distance. The higher the gate density, the stronger the ability of absorbing scattered rays. Grid ratio: the ratio of the height of the lead to the distance between the lead bars. The larger the gate ratio is, the stronger the ability of filtering rays is, and the stronger the ability of absorbing scattering lines is. At the same time, it will increase the amount of original rays absorbed. The distance from the focal point of the X-ray to the focal point of the X-ray.
