X-ray grids are classified by structure

The x ray grids are classified by structure:
1 convergence grid: each lead strip is inclined to the focus, that is, the lead strip extension line is concentrated in the focus
2 parallel grid: each lead strip is parallel to each other in the vertical plane
3 cross grid: composed of two parallel grids, the lead strips are 90° apart

4 arc grid: from the center to the outward expansion of the same radius, tile-like
According to the material:
1 commonly used grids: internal spacers are composed of non-metallic materials, such as wood chips, paper sheets, plastics and other non-metallic low-density materials;
2 full metal grid: the internal spacer is metal material: aluminum sheet. Its high strength and good moisture resistance;
