摘要： An x-ray radiator has an x-ray tube with a deflection arrangement that deflects the electron beam of the x-ray tube dependent on a control signal such that the position of the focal spot on the anode corresponds to a reference position changing as a function of time. A detector acquires the actual position of the focal spot and a control unit is supplied with the actual value signal and a reference signal and generates the control signal.

摘要： A distance sensor is provided for supplying a precise distance signal identifying the spacing between two components in a computed tomography apparatus which move relative to each other. The two components may be, for example, the rotating scan frame and the stationary gantry inside of which the scan frame rotates. The distance sensor includes a measuring mark mounted on one of the components and having a geometrical shape, such as the shape of a triangle tapering toward the other component, so that the measuring mark influences, such as by interrupting, the path of a measuring light ray which is emitted from the other of the components. The time during which the measuring mark influences the measuring light ray is dependent on the spacing of the components from each other. A signal indicative of this spacing is supplied to an evaluation circuit, and can be used to identify deviations from a specified rotational center of the scan frame with a high degree of resolution, so that appropriate correction steps can be undertaken.

摘要： A data acquisition and data reduction system (DERS) are disclosed for acquiring and compressing image data generated and loaded by an image data detection unit (DE) of an imaging system (BGS) in which the data acquisition and data reduction system (DERS) is integrated. The imaging system (BGS) can, for example, in this case be a conventional x-ray, computed tomography or magnetic resonance tomography machine for high resolution radiographic, CT or MRI based display of interesting tissue regions of a patient to be examined. At least one embodiment of the present invention relates chiefly to a data compression module (DKM) integrated in the front end of the data acquisition and data reduction system (DERS), and to an associated method for acquiring comprised image data with the aid of which the data throughput rate of an image processing and image visualization system (BVS, AB) connected to the x-ray, CT or MRI machine can be improved. In order to accomplish the data reduction, in addition to loss free, reversible compression and coding methods that are operated, for example, using the principle of run length coding, Shannon Fano entropy coding, Huffman coding or Lempel Ziv Welch coding, it is also possible in at least one embodiment to use lossy compression and coding methods that are based, for example on the principle of discrete cosine transformation, wavelet transformation or geometric or fractal image compression.
