Chronic obstructive lung disease (COPD) is one of the most prominent causes of death in the industrial world. Current clinical research is aimed at developing treatment methods. For this, quantitative staging and monitoring of the disease is highly important, including the differentiation between airway-dominant disease and parenchyma-dominant disease. Moreover, selected cases of severe emphysema benefit from lung volume reduction using surgical, and, more recently, minimally invasive techniques such as bronchial valves. Regional image analysis is crucial for selecting patients and planning these procedures.
Solutions & Features
Our software focuses on the following aspects for COPD diagnosis:
- Segmentation of lungs, lobes and segments

The lung and lobe segmentation algorithms won first prize in the Lung and Lobe Segmentation Challenge held at the MICCAI 2011 conference (LOLA11).
Parenchyma and airway analysis is integrated into the Pulmo3D software used by numerous sites for clinically researching and evaluating COPD diagnosis, intervention planning, and monitoring. Quantitative parenchyma and airway analysis has been successfully applied to more than 1000 datasets.
