  • Anti-Scatter Grid for an X-Ray Device with Non-Uniform Distance and/or Width of the Lamellae
    Publication number: 20090003530
    Abstract: An anti-scatter grid (5) for an X-ray device, comprising a plurality of lead lamellae (51) focussed downward and a fixed grid-focus distance (202) and having a filler material (52) therebetween. The width of the lamellae (51) at the edges of the grid (5) is less than that at the centre of the grid (5), and/or the width of the filler material portions (52) is greater at the edges than at the centre of the grid (5). Thus, when the source-to-image distance (SID, 203) varies relative to the grid-focus distance (202), the transmission of the primary radiation beam at the edges of the grid (5) is not adversely affected.
