Title:
HIGH PRECISION MODELING OF A BODY PART USING A 3D IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO2002037423
Kind Code:
A3
Abstract:
A method and apparatus is disclosed for modeling a body part with a high precision. Image data of a body part is collected from an imaging system with a first resolution. After processing the image data collected from the imaging system, a 3-dimensional description of the body part is generated, the 3-dimensional description of the body part having a second resolution higher than the first one. A 3-dimensional parametric description of the body part is then generated. The 3-dimensional parametric description may be used to create a replica of the body part or an implant tightly fitting the said body part.
