Novel Hexahedral Meshing Algorithms

Objective:

• Develop and integrate novel hexahedral meshing algorithms into the NA-MIC kit

Progress:

• Base projection algorithms have been developed and will be integrated into the toolkit. The algorithms have been implemented in KWWidgets in IaFeMesh to simplify integration into Slicer3.
• The base code and algorithms have been brought into Slicer3 for integration within the GUI and MRML. Curt Lisle has been working on a this integration.
  1. The sort term goal is to get a single editable bounding box working within Slicer3 for the next release.
  2. Projection based morphing and mesh interpolation will be required.
  3. Include export to Abaqus format

• Develop mapped meshing techniques that include an FE based solution using ITK that registers a template mesh with a subject specific surface.

To Do:

• Fully support all bounding box editing options
  1. Add
  2. Delete
  3. Split
  4. Merge
  5. Extrude
  6. Face manipulation

• Extract mesh material properties from the images

• Further evaluate and integrate the mapped mesh algorithms into Slicer3.

Key Investigators:

• Iowa: Nicole Grosland, Vincent Magnotta, Kiran Shivanna, Curt Lisle, and Steve Pieper
