to the Research Seminar 'Computer Graphics, Image Processing, and 
Visualization'

     on Wednesday, September 9th, 2015, at 1:15 PM,
     in Room P-702 in the Paulinum, Augustusplatz.


The talk is given by

     André Reichenbach

     Institute of Computer Science
     Leipzig University

and is entitled

     "Fiber Stipples for Crossing Tracts in Probabilistic Tractography".

Abstract:

     Given diffusion weighted magnetic resonance (dMRI) data, tractography
     methods may reconstruct estimations of neural connections of the human
     brain, so called tractograms. Probabilistic tractography algorithms
     generate a scalar value for each point of the brain, which 
describes the
     confidence of an existing structural connection to a predefined seed
     region. Recently presented Fiber-Stippling is a promising tool to
     effectively visualize such scalar values on axis aligned cutting 
planes.
     However, Fiber-Stippling only works with principal diffusion 
directions and
     cannot handle complex tract configurations, such as overlapping or 
crossing
     tracts, which are very important to neuroscience. In this talk I will
     present an illustrative technique for probabilistic tracts in such
     configurations, which is based on Fiber-Stippling. This technique 
supports
     multiple diffusion directions as given by high angular resolution
     diffusion images (HARDI) and hence can visualize crossing tracts, while
     preserving all of the advantages of Fiber-Stippling.


On behalf of Professor Scheuermann all those interested are cordially 
invited to attend.


Yours sincerely,

Tom Liebmann
