Abstract
Methods for making large area grids consisting of focused and unfocused holes in sheets of metal. The grid consists of thin metal walls surrounding hollow openings. The projection of all walls converge to a focal spot in the focused grid, and on parallel or substantially parallel in an unfocused grid. A grid having a large area is made by interlocking together smaller grid pieces. A tall device is made by stacking layers of focused grids. Methods to make unfocused grids that detect parallel incoming x-rays are also described. The opening of the grid can be filled with phosphor or other scintillating materials to make a integrated grid/scintillator structure. These grids can also be applied to many applications such as x-ray antiscatter for diagnostic medical imaging, non-destructive testing, x-ray collimation, filters for liquids or electromagnetic radiation.
