A method for generating a radiologic three-dimensional digital volume tomography image of a patient's body part includes fixing a marker support to the patient's body part. The marker support is provided with a non-radioopaque support body in which a plurality of radioopaque marker elements are affixed. A nominal size S and/or a nominal distance D of the radioopaque marker elements to each other is known. The body part is image recorded with a digital volume tomography device so as to generate a three-dimensional raw image of the patient's body part. A size S′ and/or a distance D′ of the radioopaque marker elements in the three-dimensional raw image is measured. An aberration value is generated by comparing the size S′ and/or the distance D′ with the respective nominal size S and/or the nominal distance D of the radiopaque marker elements. The three-dimensional raw image is corrected with the aberration value.
