Airway Inspector is a free open source tool for CT-based image quantitative analysis of the lung. It provides the tools that clinical scientist can used to explore airway morphology and desitometric characteristics. Airway Inspector is the gateway to phenotype airway diseases.
Airway Inspector is maintained by the Applied Chest Imaging Laboratory (ACIL) and is based on the 3D Slicer. The 3D Slicer is a general purposed open source platform for medical image analysis maintained by the Surgical Planning Laboratory at Brigham and Women's Hospital, Boston, MA.
