Goals Develop a methodology for centerline detection in intrathoracic airway trees.
Methods I, IP 3D skeletonization, 3D connectivity. Methods I, AI Traversing a 3D graph, identifying bifurcations. Methods I, AI Implement 2D graph search on 2D projections of each of the sutures to find X-Y coordinates of 3D line. Follow this by projecting this back into the 3D volume. Validation Quantitatively compare automatically detected suture lines with manually determined suture lines in at least 10 subjects.
