3D Virtual Bronchoscopy Navigation System

Virtual bronchoscopy (VB) plays an important role in the evaluation of chest diseases. Our goal is to develop a new Virtual Bronchoscopy Positioning and Navigation system (VBPN) to control the reality and virtual environment simultaneously, which can guide the bronchoscopy to the destination according to the data from sensor. The VBPN is composed by pre-processing and interactive simulation framework. This paper researches the key technologies of VBPN, including airway tree segment, centerline analysis, path planning. The experiment results show that it can view the trachea and more deep bronchial branches from the different angles.
