Paper Abstract

Surface reconstruction from cross-sectional contours has become increasingly important in medical image applications. In this paper, a method of reconstructing the surface of an object based on the descriptions of cross-sectional contours has been developed. Each cross-sectional contour is first partitioned into convex/concave segments based on the relative locations of points on the contour. Each segment of the contour is then described by a parametric cubic polynomial, and the boundary is recovered based on the description. A matching technique incorporating possible deformations between adjacent cross-sections is used to obtain the correspondence between adjacent cross-sectional contours. Once the correspondence is established, the surface between correspondent segments of adjacent crosssectional contours is reconstructed by a traditional triangulation technique. As the reconstruction is based on the shape of the cross-sections, the reconstructed surfaces are more close to that of the original object.
