Streamline Visualization of Diffusion Tensor Data Based on Triangle Strips [chapter]

Dorit Merhof, Markus Sonntag, Frank Enders, Christopher Nimsky, Peter Hastreiter, Günther Greiner
Bildverarbeitung für die Medizin 2006  
For the visualization of diffusion tensor imaging data, different approaches have been presented such as scalar metrics, glyphs or streamlines.  ...  However, the number of streamlines for a tracking of the whole brain or very dense tract systems may be immense, making a mesh-based tube visualization inefficient.  ...  Acknowledgments This work was supported by the Deutsche Forschungsgemeinschaft in the context of SFB 603, Project C9 and the Graduate Research Center "3D Image Analysis and Synthesis".  ...

Dorit Merhof, Markus Sonntag, Frank Enders, Christopher Nimsky, Peter Hastreiter, Guenther Greiner
2006 IEEE Transactions on Visualization and Computer Graphics  
Diffusion tensor imaging is of high value in neurosurgery, providing information about the location of white matter tracts in the human brain.  ...  The triangle strips follow the fiber streamlines and are textured to obtain a tube-like appearance. A vertex program is used to orient the triangle strips towards the camera.  ...  ACKNOWLEDGEMENTS This work was supported by the Deutsche Forschungsgemeinschaft in the context of SFB 603, Project C9.  ...

Visualizing Uncertainty in HARDI Tractography Using Superquadric Streamtubes [article]

Vitalis Wiens, Lara Schlaffke, Tobias Schmidt-Wilcke, Thomas Schultz
2014 Eurographics Conference on Visualization  
Standard streamtubes for the visualization of diffusion MRI data are rendered either with a circular or with anelliptic cross section whose aspect ratio indicates the relative magnitudes of the medium  ...  As a secondcontribution, we apply our novel superquadric streamtubes to visualize uncertainty in the tracking direction ofHARDI tractography, which we represent using a novel propagation uncertainty tensor  ...  The diffusion tensor, a symmetric 3 × 3 matrix, is the simplest model that captures this data [BMLB94] , and streamtubes are one of the most widely used tools for visualizing it [VZKL06] .  ...

Flow field visualization using vector field perpendicular surfaces

Karljohan Lundin Palmerius, Matthew Cooper, Anders Ynnerman
2009 Proceedings of the 2009 Spring Conference on Computer Graphics - SCCG '09  
These surfaces are a perpendicular analogue to streamlines, with the vector data always being parallel to the normals of the surface.  ...  This paper introduces Vector Field Perpendicular Surfaces as a means to represent vector data with special focus on variations across the vectors in the field.  ...  When visualizing diffusion tensor data this might not produce noticeable artifacts, however the occurrence of helicity must be correctly handled in the generalization of this concept.  ...

Crease Surfaces: From Theory to Extraction and Application to Diffusion Tensor MRI

T. Schultz, H. Theisel, H.-P. Seidel
2010 IEEE Transactions on Visualization and Computer Graphics  
Finally, we show that DT-MRI streamsurfaces, which were previously used for the analysis of planar regions in diffusion tensor MRI data, are mathematically ill-defined.  ...  We used the software teem (teem.sf.net) both for its implementation of the marching cubes-based crease extraction and as a framework for our own implementation.  ...  Thus, we propose an alternative, well-defined set of surfaces to visualize planar regions of DT-MRI data, based on height creases.  ...
