Title: Method of registering surfaces using curvature

Abstract: A patient surface is registered with a model surface based on curvature byacquiring patient range data and determining the curvature of the patientsurface based on the range data. The patient surface is generated andshaded based on the curvature. A model surface is generated from imagedata and processed to determine the curvature of the model surface. Themodel surface is shaded to represent the curvature. The shaded patientsurface and the shaded model surface are aligned in registration with eachother by manipulating the patient surface and/or the model surface untilthe curvature features coincide.
