Abstract

The invention relates to a method and a device for processing a volumetric image record. The method comprises the following steps: carrying out a non-optical image scanning method on an object to be analysed and generating a volumetric image record and extracting the object contour from the volumetric image record in order to determine the position of the object surface; defining an object surface point and a surrounding area for said object surface point and analysing the grey tones within the surrounding area; calculating a quality value, which reflects the localised quality of the surface, for the object surface point on the basis of the grey-tone analysis. The device comprises equipment for carrying out the method.
