Abstract

A method for creating geometrical models of tubular anatomical structures is described. This method takes advantage of the cooperation between two processes: one of them is automatic and is based on the Delaunay triangulation of a set of points, the other one is interactive and is based on the matching of a user defined model with a set of points. The automatic approach goes through a geometrical analysis of the data set; thus it provides information which reduces the interactive part of the other process. The final result is a continuously shaped geometrical model which is associated quite automatically with the initial set of points
