Abstract

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.
