摘要： The invention relates to a method for optimizing the throughput when processing images from X-ray computer tomographies (CT). The proposed method for handling or processing image data from individual images or consecutive images is based on a substantially punctiform radiation source (70), by which an object (1) to be captured or reconstructed is depicted on a flat detector (80) readable as a screen. A plurality of processing strips (T1, T2) of the image are read at the detector (80), wherein each strip (T1, T2) takes up an image portion. The image portion is associated by a respectively associated volume layer (V1, V2) of the object (10) with respect to the radiation path of the radiation source (70). A respective image data portion in a respective processing strip (T2) is fed to a processing unit (E2). Each volume layer (V1,V2 , V6) of the object can hereby be reconstructed; a respective volume layer is reconstructed by one - of a plurality of - processing units (E1,E2 ,E6).

摘要： The invention relates to a compact device and a method for recording an image. A mirror arrangement is interposed between an image source and a detector to record an image that is produced by the image source. The mirror arrangement comprises two interspaced deviating mirrors that are parallel to each other or that form an acute angle smaller than 90°. Particularly when the image source is a scintillator layer a screening from X-rays can be achieved in front of the detector.

摘要： The present invention provides an apparatus and a method for reducing transition artefacts in an overall image composed of partial images whose image areas have overlap areas. The apparatus comprises a device for storing image data of the pixels of the partial images and a device for generating the overall image, on the basis of the image data of the partial images by superposition of the image data of the pixels in the overlap area in accordance with a weighting, wherein the weighting is formed in such a way that an influence of a pixel of a partial image which would cause an artefact in the overall image is reduced in the overall image.

摘要： A camera for optically capturing a screen, wherein the screen has an area and wherein a predetermined overall resolution is provided for the optical capture, comprises a camera support with an array of camera mounts, an array of optical individual cameras as well as an image processing device for processing digital individual images of the array of optical individual cameras to generate the optical capture of the screen with the predetermined overall resolution. The image processing device is effective to reduce a correction of the individual images with regard to alignment inaccuracies and/or parameter variations, wherein for correction purposes a correction resolution is used, which is higher than the overall resolution, and wherein for every individual camera an individual correction rule is used for the correction. After the correction has been performed, the corrected overall image is brought to the predetermined overall resolution by combining adjacent pixels. Thereby, with inexpensive individual cameras, an image of a large-format screen is obtained efficiently, inexpensively and with little artifacts.

摘要： The apparatus has a detector (120) for receiving radiation deflected by a mirror arrangement (110), where the detector is arranged within a light path of X-radiation (99). The mirror arrangement includes two mirror spaced apart from one another and forming an angle of less than 90 degrees between them, where the mirror arrangement shields some X-radiation which penetrates a scintillator layer from the detector, such that X-radiation passing through the scintillator layer does not arrive directly at the detector, and passes through the mirrors, for protecting the detector from X-radiation. Independent claims are also included for the following: (1) a method for detecting an image (2) a method for manufacturing an apparatus for detecting an image.
