Paper Abstract:
|
In a medical context, we reconstruct a surface from a sparse point cloud. The output of the 3D processing must be the input in a mechanical solver (FEM) to characterize the stress applied to the organs through the constitutive laws. To be as generic as possible, we construct a parametric surface. This surface is defined by a single B-spline patch, providing an easy way to parameterize, as well as a wish of the FEM team which operates on the resulting hexahedral model after the addition of the thickness. We present a method to automatically construct discrete offsets layers based on the physiological thickness of each organ. |
