  • Anti-scatter grid
    Patent number: 7839981
    Abstract: An anti-scatter grid for medical x-ray devices is provided. The anti-scatter grid comprising a number of first elements from a first material with second elements made from a second material integrated therein. In this case the first material is more transparent to radiation than the second material. The second elements are arranged in the first elements such that for stacking of the first elements a grid absorbing scattered radiation is formed by means of second elements for radiation arriving perpendicular to the direction of the stacking of the first elements. The advantage of this is that this anti-scatter grid is able to be produced simply and reliably with a large aspect ratio.
