Patent ID: 7149283

Claim:
A method for producing and applying at least one of an antiscatter grid and collimator to at least one of an x-ray and gamma detector having an array of detector elements which form a detector sufface with detection regions sensitive to at least one of x-radiation and gamma radiation and less sensitive intermediate regions, comprising: producing a basic structure through layer-wise solidification by using a rapid prototyping technique to form transmission channels and intermediate walls of at least one of the antiscatter grid and collimator, including at least in a first direction a center-to-center spacing at least one of equal to and an integral multiple of a center-to-center spacing of the sensitive detection regions of the detector; coating the intermediate walls with a material which strongly absorbs at least one of x-radiation and gamma radiation; and applying at least one of the antiscatter grid and collimator to the detector surface and connecting at least one of the antiscatter grid and collimator to the detector surface in such a way that at least one of the intermediate walls running perpendicular to the first direction and their coating, are situated over relatively less sensitive intermediate regions of the detector surface.
