Abstract:
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.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
