Abstract
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.
