CT image-based segmentation, 3D reconstruction and SLA printing of human trachea

Several recent studies have demonstrated the feasibility and utility of trachea CT 3D reconstruction, including its ability to enhance the accuracy and safety of surgical procedures. This paper tries to emphasize on the fabrication of the 3D model of the trachea and on a pioneer study that would put in the spotlight the utility of 3D printing and reconstruction of human respiratory airways. While the fabrication process represents an important step in creating such complex geometries, it is important to understand the post-production procedures and how to apply them to obtain a geometry that will later be used in imaging and experimental simulations.
