Semi-automated Preoperative Resection Planning

(57) ABSTRACT Preoperative resection planning is assisted by a computer. Rather than rely on interpolation of the user input, a graph of interconnections is used. The user inputs one or more polylines on one or more two-dimensional vieWs. The polylines are used to assign resection and remnant seeds With a band of unassigned locations. The 2D seeds are used With the graph of interconnections to assign different voxels in the volume, including the unassigned locations, as being part of the resection volume or part of the remnant volume.
