Abstract: A method is proposed for producing an anti-scatter grid or collimator for a radiation type, which is formed from at least one base body of prescribable geometry having transmission channels or slits for primary radiation of the radiation type which extend between two opposite surfaces of the base body. The base body is formed from a structural material that strongly absorbs the radiation type, either using the injection molding technique or by way of the technique of stereolithography. The method can be used to produce an anti-scatter grid or collimator with high accuracy and with the aid of only a few steps.

Abstract: In the current invention, a paraffin or waxy substance is added to a solvent-based parquet adhesive to generate a contiguous film that forms a barrier layer between the adhesive and the surrounding air. This barrier prevents volatile solvents from escaping and contaminating the surrounding air before parquet laying. The protective film can then be destroyed by laying down the parquet strips on the substrate. This process overcomes disadvantages to using state of the art solvent-based adhesives which are susceptible to undesirable swelling of parquet wood and contamination of air.

The discharge vessel is formed layer by layer using a stereolithography system. Preferably, the layers are formed by locally exposing the ceramic-resin mixture to a UV light source that solidifies and cures the resin only in the areas which correspond to the particular cross-sectional profile of the discharge vessel for a respective layer.

Abstract: A method is for producing and applying an antiscatter grid or collimator to an x-ray or gamma detector having matricially arranged detector elements which form a detector surface with detection regions sensitive to x-radiation and/or gamma radiation and less sensitive intermediate regions. In the method, a basic structure is firstly produced for the antiscatter grid or collimator by way of a rapid prototyping technique, through which transmission channels and intermediate walls of the antiscatter grid or collimator are formed which have at least in a first direction a center-to-center spacing which is equal to or an integral multiple of a center-to-center spacing of the sensitive detection regions of the detector. The intermediate walls are coated with a material which strongly absorbs x-radiation and/or gamma radiation in order to finish the antiscatter grid or collimator.
