Patent ID: 6980629

Claim:
A method for producing at least one of an antiscatter grid and collimator for a radiation type, formed from a base body of predeterminable geometry having transmission channels for primary radiation of the radiation type which extend between two opposite surfaces of the base body, comprising: setting the geometry of the base body; constructing the base body according to the set geometry by use of a rapid prototyping technique through layer-wise solidification of a structural material, the structural material being substantially transmissive to the radiation type, under the action of radiation; and coating inner surfaces of the base body in the transmission channels with a material, which strongly absorbs the radiation type, up to a layer thickness which suffices to absorb virtually completely incident secondary radiation of the radiation type, wherein the opposite surfaces of the base body have, at most, a coating made from the material strongly absorbing the radiation type and having a thickness not greater than the thickness of the coating on the inner surfaces.
