摘要： 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. Subsequently, the antiscatter grid or collimator is applied to the detector surface and connected to the detector surface in such a way that at least the intermediate walls running perpendicular to the first direction, or their coating, are situated over the less sensitive intermediate regions of the detector surface. A detector having an antiscatter grid or collimator in which no moiré interference occurs can thus be realized in a simple way.

摘要： A method is for producing an antiscatter grid or collimator for a radiation type, which is 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. In the method, the base body is constructed by use of a rapid prototyping technique by layer-wise solidification of a structural material, which is substantially transmissive to the radiation type, under the action of radiation. Inner surfaces of the base body in the transmission channels are coated with a material, which strongly absorbs the radiation type, up to a layer thickness which suffices to virtually completely absorb incident secondary radiation of the radiation type. The opposite surfaces of the base body are not coated, or are aftertreated in such a way that they do not bear a coating or bear a coating of greatly reduced layer thickness made from the material strongly absorbing the radiation type. The method permits the simple production of an antiscatter grid or collimator with high primary beam transparency.

摘要： An antiscatter device, such as a grid or collimator, is for absorption of secondary radiation which is scattered by an object. The antiscatter device includes an absorption structure with a plurality of elements. Two or more elements form a cell-like structure with a beam channel for primary radiation. Further, the elements and thus the cell-like structures are arranged and/or formed such that the absorption structure has a non-regular, aperiodic pattern.

摘要： An X-ray diagnostic apparatus has an X-ray source that emits a diverging X-ray beam bundle that strikes a planar X-ray image converter at various angles, the converter having a substrate, image elements on the substrate arranged in a matrix with a semiconductor layer and a layer that absorbs X-ray beams. The X-ray-absorbing layer is fashioned thicker in the region at which a perpendicular ray of the X-ray beam bundle strikes the detector than in the region at which an oblique ray strikes, so that the reduction of the modulation transfer function in the region of an oblique beam incidence remains as small as possible.

摘要： In an arrangement having an X-ray detector or a gamma detector with detector elements arranged in a matrix in row and column directions that form a detector surface with detection regions that are sensitive to X-rays or gamma radiation and insensitive intermediate regions, and a stray radiation grid or collimator of absorbent structure elements that is arranged over the detector surface, the absorbent structure elements proceed over the intermediate regions and are fashioned such that their detector-side center-to-center spacing in the row direction and/or column direction is greater by a whole-numbered factor than the center-to-center spacing of the detector elements in the same direction, and/or sections of the absorbent structure elements that proceed in one direction exhibit a lower height than sections that proceed in the respectively other direction. Moiré effects can be avoided in the image exposure and, at the same time, a reduced primary radiation absorption by the stray radiation grid or collimator is achieved even given a moving radiation source.
