Patent ID: 8351670

Claim:
A region data editing apparatus comprising: a data obtaining section for obtaining region data which represents a region of a three-dimensional space which region has been extracted from a three-dimensional image; a specifying operation receiving section for receiving a cross section specifying operation in which a cross section of the three-dimensional image is specified; a deforming operation receiving section for receiving a contour deforming operation in which a contour of the region on the cross section which has been specified by the cross section specifying operation is deformed; a boundary surface deforming section for deforming a boundary surface between inside and outside of the region in such a manner that the boundary surface follows the contour deformed by the contour deforming operation; and a region data updating section for updating the region data in such a manner that the region data thus updated represents an inside of the boundary surface which has been deformed by the boundary surface deforming section; wherein the three-dimensional image is obtained by capturing an image of a living body; and wherein the region corresponds to an organ or a bone structure tissue in the three-dimensional image.
