Reconstruction of tracheobronchial tree and measurement of airway dimensions. One axial image of chest CT scan (a) and reconstructed image of tracheobronchial tree (b) for a study subject were presented with the candidate airway for measurement highlighted by the red line. The airway straightened was shown in C with the measurement spots for the 6th and 9th generations labeled by the red lines. The cross-sectional images of airways for dimensional measurement were presented in D (6th generation) and E (9th generation) with lumen diameter and wall thickness labeled
