Main parameters of x-ray grid.

The x-ray grid should be placed between the human body and the film, and most of the scattered rays can be filtered out, only a small part of the scattered rays can be missed.

The x-ray grids are divided into common x-ray grids and all-metal x-ray grids according to the material.

Commonly used x-ray grids: the internal spacer is composed of non-metallic materials, such as wood, paper, plastic and other non-metallic low density materials; all-metal x-ray grids: the internal spacer is metal material aluminum, its strength is high, moisture resistance is good.

Three parameters are particularly important when customers consult the x-ray grids. Focus: The vertical distance from the lead convergence line to the grid surface, F. Gate ratio: It is also the ratio of height of lead bar to gap of lead bar, R. Gate Density: Number of lead bars per unit distance, N.
