We developed an algorithm for automated segmentation and quantification of the human airway tree from the CT images of the lung. The algorithm consists of segmentation of the airway tree, its skeletonization, identification of the airway generation, and measurement of volume, length and diameter of each airway. The airway lumen was extracted from CT images with the region growing method. For morphometric identification of airways' branching, the 3-D airway model was skeletonized. The results showed it was possible to extract up to the 14th generation of the airway tree whose diameter was 1.7mm. The airway diameters obtained were in good agreement with those reported in autopsy study, although the diameters on and after 8th generation were all larger than those in vivo measurement due probably to an insufficient resolution of CT images. These results addressed the potential of the algorithm developed in this study for quantification of the airway tree.
