Figure 3:

Reference airway segmentation results on standard-dose total-lung-capacity CT data from phase II visits of the Genetic Epidemiology Chronic Obstructive Pulmonary Disease Iowa cohort (Data CII-Stand). (A) Mean airway counts at different airway tree generations. (B) Mean and SD of airway detection rates at different generations. (C) Representative reference airways for different groups segmented at standard radiation. The representative participant for each group was selected as the one with the total airway count closest to the respective group mean. COPD = chronic obstructive pulmonary disease.
