Abstract:
1. A method for analyzing a data set of an object to be examined, which data set comprises voxels of at least a first type and a secondtype, said method comprising the steps of: classifying the voxels as voxels of the first, the second or further types; thereafter determining which of the voxels of the first type are boundary voxels that adjoin voxels of the second or further types; thereafter assigning a data value to each voxel of the first type, said data value representing a measure of the distance between said voxel and the nearest boundary voxel; thereafter classifying the voxels of the first type that have a distance data value exceeding a predetermined threshold as aberration voxels indicative of an aberration in the object; thereafter determining which of the aberration voxels are boundary abberration voxels adjoining non-aberration voxels of the first type; and thereafter adding a number of voxels of the first type that form a shell of a certain thickness to the aberration voxels.
