摘要： A method for correcting a detector configured to generate object radiographs and an arrangement to implement the method is provided. The method includes the steps of (a) providing the detector having setting values for a gain and offset correction, (b) capturing a plurality of object radiographs of a test object by the detector and generating a reconstructed three-dimensional representation of the test object based on of the object radiographs, (c) determining at least one quality value of the reconstructed three-dimensional representation, repeating the steps (b) and (c) at least once, wherein before the repetition, a parameter set is generated and a measurement sequence is implemented on the basis thereof, at least one setting value for a gain and offset correction of the detector being determined anew based on the measurement sequence; and (e) determining a preferred gain and offset correction based on overall determined quality values.

摘要： A variable stop apparatus for arrangement between an X-ray source and an object to be measured in a CT-scanner and a CT-scanner including the variable stop apparatus are provided. The variable stop apparatus includes a stop carrier that is pivotable about a pivot axis. The stop carrier has at least two stops. The at least two stops are in each case configured to be brought into a predetermined angular position by pivoting the stop carrier. The at least two stops are arranged at different longitudinal positions with respect to a longitudinal direction that is defined by the pivot axis.

摘要： An x-ray examination arrangement includes an x-ray radiation source arranged at a source position, at least two x-ray detectors having active detector areas and being arranged such that the active detector areas capture different solid angle ranges with respect to x-ray radiation produced by the x-ray radiation source and emanating from the source position, and a control device configured to calculate a projection onto a virtual detector plane based on radiographs respectively captured by the at least two x-ray detectors and spatial poses of the at least two x-ray detectors relative to the source position, and provide a combined radiograph for the virtual detector plane based on the projection. In addition, a method for operating the x-ray examination arrangement and a computed tomography device are provided.

摘要： A calibration configuration calibrates a coordinate measuring machine that is suitable to irradiate measurement objects with invasive radiation and to process corresponding radiographs of the measurement objects. The calibration configuration includes a plurality of calibration modules. Each calibration module includes a carrier and in each case a plurality of at least three calibration objects that are assigned to the carrier. The plurality of calibration objects are arranged along a longitudinal direction of the calibration module and attached to the carrier.
