In a method and an evaluation device for determining the position of a structure located in an object to be investigated by means of X-ray computer tomography, a cutting data record, which images the object in a cutting plane, is determined from a volume data record of the object. The cutting data record is binarized to form a binary data record, in which the structure voxels imaging the structure and the surface voxels imaging an object surface are determined. To determine the position, a distance data record is produced in such a way that a distance value, which characterizes the smallest distance of the respective distance voxel from the surface voxels, is assigned to each distance voxel of the distance data record. The distance voxels corresponding to the structure voxels are then determined and the associated distance values evaluated.
