Table 1.
Summary route-definition results using the proposed system for a human peripheral bronchoscopy study. Cases are numbered according to an IRB Protocol (the study began with case 24. Missing cases, such as 31, involve consented patients for whom no data was collected). Route length = total number of bronchial generations, starting from the trachea traversed by an ROI route. Missed airways added to a route during defect correction are listed by bronchial generation number for airway tree augmentation and branch addition; “none” indicates that a route had no observed defects. The two distinct RUL routes for case 38 exhibited the same defects, making defect correction efficient. These two routes terminated at different generation 8 locations. LUL left upper lobe, LLL left lower lobe, RUL right upper lobe
