A method is disclosed for an x-ray device and a computer tomograph for suppressing beam hardening artifacts in a generated image of an object, for example in a tomogram of a patient. In the method, N measured values are acquired relating to N different energy ranges of the x-radiation. Further, one pseudomonochromatic measured value is calculated in each case from the N measured values such that there is generated from different projection directions on the basis of the calculated pseudomonochromatic measured values, an image in which beam hardening artifacts are substantially suppressed.
