Description of a Fully Automatic Lung Segmentation Algorithm Based on the Cognition Network Technology

Accurate and fully automated segmentation and quantification of organs are prerequisites towards operational computer aided diagnosis and therapy control systems. The Definiens Cognition Network Technology presented in this paper provides a framework for rapid development and scalable execution of image analysis solutions. The Cognition Network Technology combines pixel-processing techniques with iterative, context-based object or segment generation and classification processes using a semantic knowledge base. We applied this technology to identify automatically left and right lungs in 3D CT data.
