Automatic airway evaluation system and method for multi-slice computed tomography (MSCT) image data using airway lumen diameter, airway wall thickness, and broncho-arterial ratio
A method for evaluating a respiratory tract in a bronchial tree includes: segmenting a bronchial tree; Modeling the segmented bronchial tree, calculating a first ratio for an airway in the segmented and modeled bronchial tree, the first ratio being a ratio between a diameter of the airway lumen and a diameter of an artery accompanying the airway; Calculating a second ratio for the airway, the second ratio being a ratio between the diameter of the artery and a thickness of the airway wall; or calculating a rejuvenation index for the airway, wherein the rejuvenation index indicates a taper of the diameter of the airway lumen; Evaluating and color-coding the first ratio, second ratio or taper index, and visualizing the segmented and modeled bronchial tree that is color-coded according to the first ratio, second ratio, or taper index.
