Selection of focal length of filter grid

Many customers consult with the filter grid, and we usually confirm with the customer the required filter grid size, grid density, grid ratio and focal length.Recently, more and more mobile DR optical machines have been used, and the focal length of the filter grid is required for the examination of patients’ bed and vertical film. For the general bed shooting, the focal length of the filter grid is recommended to be 1m, while the focal length of the filter grid is 1.8m for vertical shooting.If the customer has a sufficient budget, he can buy two filter grids with different focal lengths. If the customer has a insufficient budget, he can buy a dual-use filter grid with a focal length of 1.3m. Although the imaging quality is not as high as that produced by the standard focal length, it is compatible with both the horizontal and vertical shooting modes.
