Abstract

In biomedical engineering many applications (C.A.T., R.M.N., microscopy) involve the representation of 3D numeric data to help in the comprehension of objects structure. In this paper we are interested in the case where the 3D object information is obtained from a sequence of 2D cross-sectional images. The proposed method is the polyhedral approximation of an object's surface by a set of triangular planar patches what is called triangulation. Although this approach has been often developed, it suffers some limitations, for instance when the contours are very distorted or when there is more than one contour by slice (multiple-contour). We propose a triangulation algorithm which provides a solution to these problems and which can be used even for complex shape objects. We present the application of our algorithm to the 3D representation of three real biomedical objects of increasing complexity.
