V---Bundles: Clustering Fiber Trajectories from Diffusion MRI in Linear Time
Andre Reichenbach,Mathias Goldau,Christian Heine,Mario Hlawitschka +3 more
- 05 Oct 2015
TL;DR: The 2D vector field k---means algorithm of Ferreira et al. is extended and adapted to find bundles in 3D tractography data from diffusion MRI dMRI data and can cluster large datasets without the use of random sampling or complex multipass procedures.

Choosing a Tractography Algorithm: On the Effects of Measurement Noise
Andre Reichenbach,Mario Hlawitschka,Marc Tittgemeyer,Gerik Scheuermann +3 more
- 01 Jan 2014
TL;DR: This paper focuses on the thermal noise that is present in all MRI measurements and compares its effect on the output of several established tractography algorithms, and indicates that among the algorithms tested, the Tensorlines approach is the most robust for tracking white matter fiber bundles and both theTensorlines and the Bayes DTI approach are good choices for calculating gray matter structural connectivity.

Combined Three-Dimensional Visualization of Structural Connectivity and Cortex Parcellation
Andre Reichenbach,Mathias Goldau,Mario Hlawitschka +2 more
- 01 Jan 2014
TL;DR: This work proposes an interactive illustrative 3D visualization for both structural connectivity data and cortex parcellations in anatomical space and employs interactivity and illustrative depth-enhancing, which help the user to build a mental map of the connections in the brain.

Fiber stipples for crossing tracts in probabilistic tractography
Andre Reichenbach,Mathias Goldau,Mario Hlawitschka +2 more
- 14 Sep 2015
TL;DR: This work presents an illustrative technique for probabilistic tracts in such configurations, which is based on Fiber-Stippling and 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.

Visualizing crossing probabilistic tracts
Mathias Goldau,Andre Reichenbach,Mario Hlawitschka +2 more
- 25 Oct 2015
TL;DR: This work suggests a visualization based on Fiber-Stippling but sensible to multiple diffusion orientations from HARDI-based diffusion models, which implies that tract crossings may now be visualized as crossing stipples, which is an essential step towards an accurate visualization of the neuroanatomy.
