Computer graphic modeling in surgery

The application of computer-based solid modeling techniques to human anatomy shows great promise for enhancing surgical instruction and research. Such advances will directly benefit patient care. The increasing availability of powerful modeling programs for the microcomputer and the interactive peripheral technologies make the delivery of this new modality practical at the present time. We continue to refine our methodology for producing accurate and esthetic anatomic models and have developed a technique for three-dimensional "sculpting" of elongated structures. We continue to explore the possibility of using sectional scanning data to create anatomic images. Several applications have been described, ranging from surgical simulations to a ballistic injury model, in order to indicate the potential scope of this powerful technology.
