Key Investigators

• UNC: Marc Niethammer

Objective

• 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.

Approach, Plan

• 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.

Progress

Delivery Mechanism

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)
