What are the conventional densities and grid ratios of x-ray grids?

Everyone knows that the grid can make the image clearer and absorb the messy scattered rays. Let’s take a look at the types of grids according to their materials and structures. According to the structure: 1 Converging grid: each lead bar is inclined to the focus, that is, the extension line of the lead bar is concentrated on the focus 2 Parallel grid: each lead bar is parallel to each other in the vertical plane 3 Cross grid: It is composed of two layers of parallel grids, The direction of the lead strips is 90° to each other. 4. Arc grid: it is formed by superimposing equal radius from the center to the outside, and tile-like. According to the material: 1. Commonly used grid: the internal spacer is composed of non-metallic materials, such as wood chips and paper chips , plastic and other non-metallic low-density materials; 2 all-metal grid: the internal spacer is metal material: aluminum sheet. It has high strength and good moisture resistance; According to the working method: 1. Static grid: At present, all static grids are used, which are fixed in the cassette for use. 2 Vibration grid (dynamic grid): In the square frame, a metal shrapnel fixes a grid. Before work, the grid is vibrated back and forth (old equipment may still be used). Our company is the agent of internationally renowned brand grids such as JPI in South Korea.
