Abstract
A method for segmenting a volume dataset is provided. During initialization a level set field within a volume dataset is initialized and an initial set of active voxels is determined in dependence upon the initialized level set field. In an iteration process the level set field for the set of active voxels is updated followed by updating of the set of active voxels. The iteration is continued until the number of active voxels is less than a predetermined threshold. Level set segmentation data are then determined in dependence upon the level set field and provided for, for example, graphical display or storage.
