Recent Advances in Fibre Orientation Estimation Using Diffusion-Weighted MRI
Diffusion-weighted (DW) MRI is sensitive to the microscopic thermal motion of water molecules on scales comparable with cellular structures. In biological tissue, the motion of these water molecules is hindered by a range of obstacles such as cell membranes, making it possible to probe microscopic properties of the tissue noninvasively in-vivo. Due to the coherent arrangement of fibrous structu...

متن کاملIn-Vivo Estimates of Axonal Characteristics Using Optimized Diffusion MRI Protocols for Single Fibre Orientation
This work presents diffusion MR protocols that allow estimation of axonal parameters like diameter and density in the live human brain. Previous approaches demand very high field experimental systems or suffer from long acquisition times and are therefore impractical for use in clinical studies. We propose a method that significantly reduces scan time by making use of the a-priori known fibre o...
متن کاملThe effect of finite diffusion gradient pulse duration on fibre orientation estimation in diffusion MRI
An essential step for fibre-tracking is the accurate estimation of neuronal fibre orientations within each imaging voxel, and a number of methods have been proposed to reconstruct the orientation distribution function based on sampling three-dimensional q-space. In the q-space formalism, very short (infinitesimal) gradient pulses are the basic requirement to obtain the true spin displacement pr...
متن کاملDiffusion MRI Registration Using Orientation Distribution Functions
We propose a linear-elastic registration method to register diffusion-weighted MRI (DW-MRI) data sets by mapping their diffusion orientation distribution functions (ODFs). The ODFs were reconstructed using a q-ball imaging (QBI) technique to resolve intravoxel fiber crossing. The registration method is based on mapping the ODF maps represented by spherical harmonics which yield analytic solutio...
