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： An x-ray video image system has a CCD sensor used in the production of a video image from an x-ray image, with an optimum image quality being achieved with a high read-out speed. A light source uniformly illuminates the CCD sensor before the production of an x-ray image. The outputs of the sensor from successively scanned image lines are supplied respectively to a main processing channel and to an adjustable measurement channel. By comparing the processed outputs of these two channels deviations of the image signal from predetermined values are identified. Components in the measurement channel are then adjusted until the deviations are substantially eliminated. Black level matching, white level matching, and linearity matching between the two channels can be accomplished.

摘要： In television transmission of medical X-ray photographs and in television X-ray fluoroscopy (e.g. during surgery), where a great brightness contrast range is presented, the illustrated system obtains a blurred video signal representative of the brightness of relatively large regions of the visible light image and adjustably selects high amplitude parts of such signal to synchronously modulate the scanning electron beam of a storage type television camera tube. In this way darker image areas are transmitted with full contrast for reproduction of fine image details as particularly required in medical X-ray technology, while excessively bright areas are attenuated to a desired degree.

摘要： In one mode, laminographic images are produced by sequentially pulsing a series of X-ray tubes, and by step-wise shifting of the image field of an image intensifier in an opposite sense so that each image of the desired layer is superimposed at the image intensifier output. The amplitude of the required magnetic deflection of the image intensifier is a function of the depth of the layer, and may be calibrated to represent the length dimension of a selected layer region. In another mode, a transverse sectional image is scanned by progressively increasing the magnetic deflection after each cycling of the X-ray sources, so as to scan at successive depths. With a video camera scanning the image intensifier output, one video line of each field may be stored for each depth, and then read out to display the cross sectional image. By storing different lines for respective different depths, oblique sections may be recorded. By sequentially pulsing right and left rows of X-ray sources in successive field intervals of the video camera, stereoscopic images may be generated, the right and left fields being suitably offset and visually differentiated (e.g. by color) for stereoscopic display.

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： 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.
