 Advances in technology have facilitated the increased use of three-dimensional image processing based on computed tomography(3D-CT). Chest CT of normal adults was performed using a 64-column multidetector row CT scanner. Visual information on bronchial lumens was extracted using OsiriX® software.

 With manual extraction of visual information of the bronchial lumens, we were able to extract information on up to the third-to fifth-order bronchi. The bronchi from which information was extracted were then labeled. Three-dimensional bronchial images were constructed using Maya® software.

 We created a three-dimensional bronchial tree using CT data and the results were used to develop software that allows the user to move, rotate, and scale it on the iPad®. This imaging program can potentially develop into a real model to be used during bronchoscopy training or as a bronchoscopy simulator. We also expect that this technology will have educational applications in bronchology.
