ABSTRACT:
The invention relates to a method for the interactive segmentation of a structure contained in an object from a three-dimensional image of the object. In an expansion mode a region expansion process is carried out, the results of said process simply being completely or partly undone again in a contraction mode. A quasi-continuous similarity measure can be used to determine whether or not a voxel belongs to the structure to be segmented. The expansion taking place in the region expansion process always involves the voxels having the largest similarity measure each time.
