TL;DR: A fusion scheme that obtained superior results is presented, demonstrating that there is complementary information provided by the different algorithms and there is still room for further improvements in airway segmentation algorithms.
A morphological-aggregative approach for 3D segmentation of pulmonary airways from generic MSCT acquisitions

TL;DR: A generic and automated 3D airway segmentation approach able to deal with a large spectrum of MSCT protocols by exploiting a combined morphologicalaggregative methodology is developed.
Airway shape assessment with visual feed-back in asthma and obstructive diseases
Catalin Fetita,Margarete Ortner,Pierre-Yves Brillet,Pierre-Yves Brillet,Yahya Ould Hmeidi,Francoise Preteux +5 more
TL;DR: A fullyautomated airway shape assessment approach based on the 3D segmentation of the airway lumen from MSCT data, evaluated on a MSCT database including twelve patients with severe or moderate persistent asthma, or severe COPD, by analyzing segmental and subsegmental bronchi of the right lung.

TL;DR: In this article, a 3D automated approach for airway wall segmentation and quantification in MSCT based on a patient-specific deformable model is developed, which is explicitly defined as a triangular surface mesh at the level of the airway lumen segmented from the MSCT data.

Ground truth and CT image model simulation for pathophysiological human airway system
TL;DR: Simulation results for physiological and pathological configurations are presented and discussed, illustrating the interest of such a modeling process for designing computer-aided diagnosis systems or for assessing their sensitivity, mainly for follow-up studies in asthma and COPD.
