'''Project'''<nowiki>: Clustering and Analysis of DTI Fibers. </nowiki>

[[Image:Namic-tractanalysis.ppt|Image:Namic-tractanalysis.ppt]]

'''Goals'''<nowiki>: </nowiki>

# Develop ITK modules for clustering DTI fibers from tractography. Using Normalized Cut algorithm of Shi and Malik. Improve efficiency.
# Collaborate with Slicer Tractography group to get perspective on different approaches to tractography and fiber tract analysis.
# Make UNC tools compatible with other NA-MIC tools
## Read NA-MIC NRRD DTI data
## Develop a tool that can convert ITK DTITubeSpatialObject files to vtkPolyData files and vice-versa. The UNC tools currently use the ITK files, while other tools use vtk files.
# Develop a generic tensor statistics computation module for fiber tract analysis. Currently implemented for and integrated into FiberViewer. Collaborate with Tom Fletcher.

'''Current Status'''<nowiki>: </nowiki>

# Working ITK implementation of clustering algorithm that is generic over objects with defined distance measure.
# Tensor statistics implemented in FiberViewer, but not yet a generic module.
# Tensor field computation for NRRD DTI data via Xiadong's NrrdDTIReconstruction tool.

'''Current Tools'''

# Fiber Tracker - Tool for tracking fibers from DTI data. http://www.ia.unc.edu/dev/download/fibertracking/index.htm
# Fiber Viewer - Tool for fiber editing, clustering, analysis. (Normalized Cut based clustering goes here) http://www.ia.unc.edu/dev/download/fiberviewer/index.htm
# SNAP - Used for defining ROI used in tracking. (included in InsightApplications).
# Data conversion tool: from nrrd to gipl/analyze.
# Fiber format conversion tool: from UNC fiber to vtk polydata.

'''Test Data'''<nowiki>: Currently using in-house data. A sample DTI dataset is available here in GIPL format </nowiki>http://www.ia.unc.edu/dev/download/fibertracking/DTI_Test.zip. Also testing on Brockton data from BIRN repository.
