Home < GPU accelerated FEM for simulation and segmentation


Key Investigators

  • Megumi Nakao and Nobuhiko Hata

Objective

We are developing a fast FEM-based mesh deformation library for interactive simulation and segmentation. The goal in this project week is summarized as

  • integrate linear FEM-based deformation algo into the slicer
  • perform deformation on specific data
  • implement GPU-based acceleration for real-time deformation

Approach, Plan

  • integrate a liner FEM solver(original C++ source) into the 3D slicer framework.
  • make tetrahedral meshes from medical images and set up physical conditions. Other mesh formats, points and surface models will be probablly accepted.
  • evaluate some deformation results qualitatively and improve the simulation.
  • try GPU-based acceleration by modifying the linear equation solver using CUBLAS library.

Progress

I will work in Wednesday, Thursday afternoon and Friday.
