The x ray grid ordered by the customer is ready to be packaged and shipped

The x-ray grid is composed of many thin lead bars and low-density substances that are easily permeable to X-rays, and are alternately arranged. In X-ray photography, the center line of the X-ray is aligned with the center of the filter grid plate, the original ray projection direction is in the same direction as the lead bar arrangement gap of the filter grid, and can reach the film through the lead bar gap to produce an image.
Because the scattered rays generated by the subject are multi-center and multi-directional, most of the scattered rays are absorbed by the lead bar, and only a small part passes through.
The ratio of the height of the lead bar of the filter grid to the amplitude of the filler is the grid ratio. The number of line pairs formed by lead bars and their spacing is commonly expressed as “line / cm”. Customers who need a grid can purchase.
