Construction of a Model of the Upper Gastrointestinal System for the Simulation of Gastroesophagoendoscopic Procedures

摘要

We describe current work on the construction of three-dimensional anatomical models of the upper gastrointestinal system, its computer navigation using a virtual endoscope, and the modeling of physical interactions of the model and the endoscope, including lens distortions and illumination conditions as well as collisions. This model will be part of a computer-simulation system for the training of gastroendoscopic procedures.
