Automated Segmentation and Morphometric Measurement of a Human Airway Tree From Multi-Detector CT Images Toward the Numerical Analysis of Pulmonary Flow Dynamics

Advancement in imaging technologies has shortened scan time of computed-tomography (CT). Recently introduced to a clinical market, 64-detector CT is capable of acquiring 64 simultaneous 0.5-mm slices with each 400-ms gantry revolution, yielding precise isotropic imaging of even peripheral airways within a single breath hold.
