Abstract

A method for designing a prosthetic device includes acquiring a three-dimensional image of an anatomical surface. A rules script for automatically performing a plurality of image processing rules using a script interpreter is executed. For each particular rule of the plurality of rules, one or more anatomical features that are relevant to the particular rule using a surface shaping engine are determined, the one or more determined anatomical features are automatically segmented from the acquired three-dimensional image using a feature detector, and the particular image processing rule is performed on the acquired three-dimensional image based on the automatically segmented anatomical features using a CAD tool. A prosthetic device design is produced based on the three-dimensional image upon which the rules of the plurality of image processing rules have been performed.
