Abstract: New multi-detector CT scanners produce very high-resolution 3D digital images of the human chest. Using these images, a detailed evaluation of the airways can be done. In particular, quantitative analyses can be performed on the airways to assess disease state and to help design stents. We propose a set of quantitative methods suitable for detailed analysis of the major airways. The methods provide measurements for all defined tree branches. These measurements include various airway diameters, cross-sectional area values, and branch properties. To facilitate the examination of these measurements, we also propose a set of visualization tools. These tools, integrated into a comprehensive virtual-bronchoscopic analysis system, enable flexible interrogation of the airways. Using phantom and human tests, we confirm the efficacy of our methods. Further, we demonstrate the utility of our methods for human airway analysis.
