Shenton. 2006. “Fiber Bundle Estimation and Parameterization.” Lecture Notes in Computer Science: 252–259. doi:10.1007/11866763_31.0302-9743http://nrs.harvard.edu/urn-3:HUL.InstRepos:28613876Individual white matter fibers cannot be resolved by current magnetic resonance (MR) technology. Many fibers of a fiber bundle will pass through an individual volume element (voxel). Individual visualized fiber tracts are thus the result of interpolation on a relatively coarse voxel grid, and an infinite number of them may be generated in a given volume by interpolation. This paper aims at creating a level set representation of a fiber bundle to describe this apparent continuum of fibers. It further introduces a coordinate system warped to the fiber bundle geometry, allowing for the definition of geometrically meaningful fiber bundle measures.en-USJournal Article2016-09-2810.1007/11866763_31
