Bronchus segmentation
WebAirway segmentation, especially bronchioles segmentation, is an important but challenging task because distal bronchus are sparsely distributed and of a fine scale. WebJul 1, 2015 · Right bronchus segmentation apart from TB was abnormal in eight cases. The left bronchus segmentation described was abnormal in only eight patients. No laryngeal anomaly was described. Sixteen (28%) patients had a CT-scan before endoscopy with tracheal bronchus described in only 8 patients (53.3%).
