Critical Review , 21 April

This is a critical review of the paper “An Airway Tree-shape Model for Geodesic Airway Branch Labeling” written by Feragen et. al. [1]. This paper presents a method for airway branch labeling by computing geodesic deformations between mathematical airway tree-shape models. The authors claim that the labeling results are good taking the large variation in the training set into account. Even though some important points in their experimental validation are not clarified, the proposed method brings novelty to the field with a geodesic deformation which simultaneously considers both airway topology and branch geometry.
