Abstract: | Human body is a natural heterogeneous object optimized in its structure and composition by natural processes over years of evolution. In this paper, B-spline solid representation method is extended to represent material composition to develop a heterogeneous model of the human body. Two different approaches, namely surface fairing and surface fit, are used to create a slice by slice model from CT scan data. Both the approaches are compared for different regression parameters. This methodology has the potential to represent internal body details accurately with fewer digital input data,with applications in FEM analysis, freeform-fabrication and tissue engineering. |
