Registration in the presence of sliding between organs
- Kitware: Danielle Pace, Stephen Aylward
- UNC: Marc Niethammer
- Conventional deformable image registration enforces smooth motion, causing inaccurate displacement measurements near sliding motion.
- Sliding motion is common in intra-subject 4D image registration problems, for example respiration-induced sliding of the lungs and abdominal organs against the chest wall.
- We have developed an image registration algorithm based on anisotropic diffusion that handles sliding motion.
- Continue algorithm validation experiments in 4D chest CT.
- Improve CLI documentation and user interface.
- Fix user experience issues of integration of TubeTK CLIs into Slicer 4.
- Improved Slicer's handling of external module paths that contain non-parseable executables
- Cleaned up TubeTK build output destinations
- Cleaned up CLI documentation and command-line options - rename parameters, improve descriptions, remove confusing options (inspired by BRAINSFit registration documentation)
This work will be delivered to the NA-MIC Kit as a Slicer extension as a CLI distributed in TubeTK (http://public.kitware.com/Wiki/TubeTK)
