Selection of focal length of grid

Many customers consult with the grid, and we usually confirm with the customer the required 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 grid is required for the examination of patients’ bed and vertical film. For the general bed shooting, the focal length of the grid is recommended to be 1m, while the focal length of the grid is 1.8m for vertical shooting.If the customer has a sufficient budget, he can buy two grids with different focal lengths. If the customer has a insufficient budget, he can buy a dual-use 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.
If you are interested in the grid, please call us.
