DTI-TK contains two features: a spatial normalization and atlas construction toolkit optimized for examining white matter morphometry using DTI data and a white matter tract-specific analysis pipeline.

...In the broad data visualization scenarios, that Excel and Flash are still the most popular visualization tools even today after long existence is probably attributed to their capabilities of empowering users to design their own visualizations. So in a narrower scope, what if domain scientists with DTI visualizations have a tool that is so easy to maneuver that they can fully control the design elements and visual components to create whatever visualization they really want in mind? Enlightened by the design of ProtoVis and Processing in the information visualization community, I attempted a visualization language as the first tool of this kind for DTI visualizations and even, more broadly, for visualizations of 3D scientific data, which is also motivated by the needs of spatial explorations in 3D SciVis.

While visualizing the diffusion tensor MRI (DTI) dataset using streamtubes, the unit (1x1x1) resolution in full volume seeding approach has been used as default parameters and the resulting tractography contains very dense geometries that causes visual complexity impeding the exploration of DTI visualizations. However, questions like "if the unit seeding resolution is optimal for visualizing either whole brain model or tract-of-interest (TOI)", "if not, what the optimal choice of seeding should be", and especially, "how quantitatively the choice of the fiber tracking parameter, seeding resolution, connects with the informativeness and meaningfulness of DTI visualizations". ...

This project was launched to further study other factors beyond those during the data processing - display factors such as screen size and stereo/mono characteristics. With this study, we expected to verify the hypothesis that, given the dense information in DTI streamtube visualization, enlarging screen and/or employing stereo would enhance the visualization of DTI dataset as a whole by improving user's task performance.

Diffusion tensor magnetic resonance imaging (DTI) is the currently unique in-vivo MRI technique for probing the distribution of neural pathways and micro-structures of biological tissues, thus promising for neurology and neuroanatomy research. However, the 3-Dimensional DTI tractography (DTT) suffers from the overwhelmingly dense resulting fiber tracts in its visualizations which substantially impedes effective exploration, tracts-of-interest (TOI) selection, for example, in the practical clinical diagnoses. ...

This project aims at a light-weighted interface for interactive DTI visualization that exhausts the benefits of simple gadgets like boxes and spheres amounted with multiple-view modality and in-situ data-centric interactions.

vIST/e is a C++ application that allows interactive visualization of various kinds of imaging datasets, both simple scalar data as well as complex high-dimensional data such as diffusion tensor imaging (DTI) and high angular resolution imaging data (HARDI). vIST/e is based on VTK, Qt and is designed as a plugin system which allows it to be extended in a flexible way. vIST/e emerged from being the main research tool of Imaging Science and Technology Eindhoven (IST/e), a major imaging group Eindhoven University of Technology, the Netherlands which brings together all university faculties involved in medical or industrial imaging. ...

A Novel Interface for Interactive Exploration of DTI Fibers

The purpose of the project is to develop a quantitative medical imaging & visualization program for use on brain MR, DTI and MRS data. It is a joint project of the Kennedy Krieger Institute & the Johns Hopkins University, Psychiatric Neuroimaging Lab

The program Visualizes the diffusion of water in the brain through ellipsoids.
