【Abstract】 Objective To build digitized visible model of the ear of the Chinese visible human and explore the role of virtual endoscopy of the inner ear. Methods On the SGI Workstation, three dimensional computer reconstructions of the ear were generated from the Chinese visible human dataset. Then structures of the middle ear and inner ear were observed by imitating the traditional endoscopy. Results The virtual model of the ear was successfully completed. The virtual endoscopy improved 3 D visualization of the middle ear and inner ear. Conclusion The virtual endoscopy stands as a promising new visualization technique for elucidation of the middle and inner ear, providing morphologic data for imaging diagnosis and otoneurosurgery.更多还原
