A method is proposed for correcting detector signals of a unit for reconstructing tomograms from projection data, in particular of a computer tomography unit, of a ray detector having a multiplicity of individual detector channels that form the projection data, attenuation values of individual X-rays being calculated after the passage through an examination object. In order to reconstruct the tomograms from attenuation values of the X-rays, the detector output signals are subjected to a nonlinearity correction before the calculation of the attenuation values.
