The difference between fixed X-ray grid and mobile X-ray grid

The X-ray filter grid is divided into fixed X-ray grid and mobile X-ray grid according to the moving mode, and divided into metal and non-metal according to the material.
Fixed X-ray grids have very high requirements on the grid ratio and grid density, because the grid ratio and grid density are too low, which will easily cause lead shadows and affect the image. Therefore, a fixed X-ray grid usually uses a high-density grid. The movable X-ray grid can also be called a filter device. It consists of grids, drive equipment and trays. Before exposure, the drive unit aligns the X-ray grid with the lead strip. The movement in the vertical direction until the exposure is completed can stop the shadow of the lead tape, so the movable X-ray grid does not require a high grid ratio and grid density, and can use low-density X-ray grid applications .
For non-metallic X-ray grid ratio and grid density, the content of the space between the grids is non-metallic, such as plastic, paper, etc., and its moisture resistance is weak. Measures must be taken to prevent moisture. The metal X-ray grid is filled with metal such as aluminum and has strong moisture resistance.
