Numerical simulation of human breathing and particle transport through a CT-based pulmonary airway geometry

Chronic respiratory illness afflicts more than a billion people worldwide. In recent years computational fluid dynamics (CFD) has been established as a paramount tool for studying treatments of respiratory illnesses. This work investigates physiologically appropriate, lobar-specific boundary conditions for numerical simulation of steady and unsteady flow through a computed tomography (CT) based pulmonary airway geometry. Particle transport is modeled in steady and unsteady flow. Analysis is conducted on flow phenomena and particle transport in both steady and inspiratory flow

A three-stage method for the 3D reconstruction of the tracheobronchial tree from CT scans

This paper proposes a method for segmenting the airways from CT scans of the chest to obtain a 3D modelthat can be used in the virtual bronchoscopy for the exploration and the planning of paths to the lesions.The method is composed of 3 stages: a gross segmentation that reconstructs the main airway tree usingadaptive region growing, a finer segmentation that identifies any potential airway region based on a 2Dprocess that enhances bronchi walls using local information, and a final process to connect any isolatedbronchus to the main airways using a morphologic reconstruction process and a path planning technique.The paper includes two examples for the evaluation and discussion of the proposal
