연구 분야: Analysis

The bronchial tree reconstruction is a challenging task due to its non-uniform topological boundaries and asymmetric branching pattern. Contrary to the conventional approaches of patch stitching and triangulation, this work uses a single-patch T-spline for the reverse engineering of human airways. The proposed methodology not only captures geometric details, but also illustrates the variation in the airway’s tissue properties along with the geometry. The process has been applied to develop a 3D airway model from the computed tomography (CT) scan data with preserved material information. The multi-material domain aids in representing airways internal details accurately. The proposed method has potential applications in fabrication, FEM analysis, and tissue engineering for complex branching structures.
