Virtual Laryngoscopy: A Real-Time Exploration of Laryngeal System based on Rapid Reconstruction Algorithm.

In this paper, we present a real-time approach for effective and automatic manipulation and navigation in a virtual laryngeal environment. Efficient algorithms are developed for 1), automatic segmentation, and 2) volume data organization and 3), surface rendering. Finally a virtual laryngoscope is built for the visualization of laryngeal systems and this visualization system is tested using CT volume data acquired from two normal subjects.
