Title: Exploring 3D DTI Fiber Tracts with Linked 2D Representations
Abstract— We present a visual exploration paradigm that facilitates navigation through complex fiber tracts by combining traditional 3D model viewing with lower dimensional representations. To this end, we create standard
streamtube models along with two two-dimensional representations, an embedding in the plane and a hierarchical
clustering tree, for a given set of fiber tracts. We then link these three representations using both interaction and
color obtained by embedding fiber tracts into a perceptually uniform color space. We describe an anecdotal
evaluation with neuroscientists to assess the usefulness of our method in exploring anatomical and functional
structures in the brain. Expert feedback indicates that, while a standalone clinical use of the proposed method
would require anatomical landmarks in the lower dimensional representations, the approach would be particularly
useful in fast and precise selection of the tracts. Results also suggest that combining traditional 3D model viewing
with lower dimensional representations can ease navigation through the complex fiber tract models, improving
exploration of the connectivity in the brain.
