TubeTK/Events/2010.09.28

Danielle

• Derived mathematical foundations for sliding organ registration work
• Learned ITK's finite differences classes, + Andinet's anisotropic diffusion implementation
• Read "An investigation of smoothness constraints for the estimation of displacement vector fields from image sequences", Nagel et al. 1986
• Worked out framework for registering Ryan's vessel data - extract .tre from .txt gold standard motion field, and register to image
• Added small test in TubeTK to convert a .tre to an image, given an example image
• Initial manual registration for Ryan's 'healthy' dataset
• Fixing up style/comment issues in TubeTK as encountered
• TODO: run Ryan's vessels through Hua's registration test

Romain

• Read Measuring Tortuosity of the Intracerebral Vasculature from MRA Images
• Filtering all Ryan's data using different iterations
• Preliminary results from tumor microenvironment segmentation
• Learning more Python
• Future
  • Learning python execution model of Slicer
    • http://www.slicer.org/slicerWiki/index.php/Slicer3:Execution_Model_Documentation:Python
  • Reviewing papers from Dr. Bullitt on tortuosity

Stephen

• USC
  • JointHistogram computation time reduced by 75%
  • ComputeContrastImage: still not converging :(
  • Pursuing additional funding
  • Presentation tomorrow: Pseudo-EM, Contrast Image
• BWH
  • SubK still not cut. Over 1 month at BWH.  :(
  • No word from BrainLAB. Time to pursue alternative
• TubeTK
  • Fixed failing tests. 2 remain
  • How integrate with slicer: vtkGeometry?
    • <geometry>
  • QtImageViewer (Ben checking-in)
  • RidgeExtractor: File IO issues
