Potential Areas of Collaboration

  1. Multimodal registrations from BWH with PLUNC
  2. ITK needs GPU codes
  3. How to put UNC code into the open source world (from BWH experience)
  4. Visual bookmarks as cf. Slicer (scene views)
  5. Tolerance and other surface color washes on textured objects
  6. Endoscopy and 3D MR segmentation: cervix
  7. AMIGO w/ endoscopy
  8. AMIGO w/ curved needles
  9. Curved needles for biopsies
  10. Optical CT inclusion
  11. FEM modeling sharings between BWH and UNC

  13. Shadie/MGRView or 3D PLUNC or 3D Slicer integration
  14. Adding cmake/software process to PLUNC
  15. Problem: how to integrate object-based coordinate systems into object models and integrate UI controls within those coordinate systems?
  16. MGRView w/ ray-cast volume rendering a la volview/vtk
  17. Inclusion of Ontario ARKit/SparKit? (adaptive RT)
  18. What can be taken from PLUNC into Slicer right away?
  19. There needs to be a remodeling of PLUNC licensing to meet the Slicer sharing philosophy
