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.

Anti-scatter grid

A method for producing a scattered radiation grid or collimator which, for an incident radiation type, has transmissive regions and nontransmissive regions of predeterminable geometry. First the geometry of the transmissive and the nontransmissive regions of the scattered radiation grid or collimator is set. On the basis of this geometry, a base body is constructed according to the geometry, optionally differing by a particular layer thickness, of the transmissive regions or the nontransmissive regions by a rapid prototyping technique through layer-wise solidification of a structural material under the action of radiation. On the basis of this base body, the scattered radiation grid or collimator is finally completed.
