Abstract

A method for creating a cutout surface for volume rendering includes providing a digitized medical image volume comprising a plurality of intensities corresponding to a 3-dimensional grid of points, identifying a surface of interest in said image volume, representing said surface-of-interest by a polygonal mesh, extracting a set of curves on said surface-of-interest where a cutout surface will intersect, extending a vector defined on one of said curves toward a viewing point, and sweeping said extended vector along said curve to create said cutout surface.
