Abstract

A method for stereolithographic construction of models including prostheses and anatomical pathology wherein CT scan data is computed to construct a plurality of two dimensional cross sectional images along one axis and the two dimensional image data is computed to create three dimensional coordinate data sets for the article to be modelled. The three dimensional data sets are then computed to obtain spaced parallel two dimensional image data sets in a second plane of the article and the reconstructed two dimensional image data sets are employed in a stereolithographic modelling apparatus to produce a three dimensional model of the article or part thereof. A prosthetic implant shaped to correct a defect in an anatomical part as well as a method for surgically implanting the implant using the stereolithographic method is also disclosed.
