Abstract

Stereolithography, a new technique of prototype fabrication developed for the aerospace industry, offers a unique way to display patient anatomy. Like current computer-aided-design (CAD) systems, it uses digital image data from CT and MR to produce a physical model. Unlike conventional CAD it does not require a cutting tool and therefore CAD tool-path limitations do not exist. The stereolithography apparatus (SLA) uses an ultraviolet laser to selectively polymerize and solidify a polymeric liquid plastic solution under computer control. The device was used to produce a model of cranial bony anatomy from CT image data providing full internal detail in the constructed model including encased sinuses, foramen, and potentially complete internal anatomy within a closed skull. The advantages and disadvantages of this technology are reviewed with an emphasis on future development.
