1. 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.

Abstract
A region data editing apparatus includes a contour deforming section for receiving a contour deforming operation in which a contour of a region in a three-dimensional image is deformed, a boundary surface deforming section for deforming a boundary surface ∂D between inside and outside of region D in such a manner that the boundary surface ∂D follows the contour deformed by the contour deforming operation, and a region data updating section for updating 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.

9. A region data editing method comprising the steps of:
-
(a) obtaining region data which represents a region of a three-dimensional space which region has been extracted from a three-dimensional image; (b) receiving a cross section specifying operation in which a cross section of the three-dimensional image is specified; (c) 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; (d) 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 (e) 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 in the step (d); 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. - View Dependent Claims (10)
