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. 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An X-ray image sensor with electronic, planar image converters covers a relatively large area without the occurrence of image gaps. A number of image converters adjoin one another in a surface, these being coupled to a scintillator via fiber optics. At least a part of the fiber optics proceeds at an angle deviating from 90.degree. relative to the image converters, such that the fiber optics adjoin one another at the scintillator but leave an area free at the image converters. This area is at the junction of two image converters that adjoin one another, and is thus an optically inactive region.

Abstract: Radio-diagnostic equipment includes an X-ray tube and a shutter which defines an aperture of modifiable size for allowing X-rays to pass therethrough. The shutter consists of a plurality of individual lamella which lie adjacent each other about the sides of the aperture and can be adjusted individually in a longitudinal direction depending on the size of the object under examination. An X-ray image intensifier and a television camera coupled to it generate a video signal and a monitor reproduces an image of the video signal. An evaluating circuit derives a control signal from the video signal which is applied to a position adjusting device including spring-like elements which can be deflected from an initial position by physical forces for controlling the positioning of each lamella.

Abstract: A transducer sensitive to electromagnetic radiation has a substrate with printed conductor runs arranged on both sides, a sensor that is sensitive to radiation glued over a large surface at the front side of the substrate, and of a thermal expansion-compensating "dummy" component connected to the back side of the substrate. The printed conductor runs have connections to one another only in the middle region of the substrate, and otherwise are free of intersections. The basic orientation of the conductor runs can be stellate or right-angled. The absence of conductor run intersections allows gas to escape during the gluing process, so that gas pockets do not form in the adhesive, which can degrade the quality of the adhesive connection.
