Abstract
We investigate the accuracy of complex anatomical replicas derived from X-ray computed tomography data linked to the rapid prototyping technique of stereolithography. Data processing by specific softwares (segmentation, three-dimensional interpolation) allows direct interfacing with the stereolithography apparatus to build a resin replica with reproduction of internal cavities. Our preliminary results about surface and dimensional accuracies suggest that the reproduction of complex anatomical structures by stereolithography is reliable enough to be used for surgical planning, for custom-made implants and for surgical anatomy teaching.
