Moderately Degenerated Human Intervertebral Disks Exhibit a Less Geometrically Specific Collagen Fiber Orientation Distribution

STUDY DESIGN Collagen fiber orientation analysis in moderately degenerated human cadaveric annulus fibrosus (AF) tissue samples. OBJECTIVE Little is known about the changes in tissue architecture during early degeneration of intervertebral disks (IVDs). As collagen organization s

On Computing the Underlying Fiber Directions from the Diffusion Orientation Distribution Function

In this work, a novel method for determining the principal directions (maxima) of the diffusion orientation distribution function (ODF) is proposed. We represent the ODF as a symmetric high-order Cartesian tensor restricted to the unit sphere and show that the extrema of the ODF

Fast Solutions for the Fiber Orientation of Concentrated Suspensions of Short-fiber Composites Using the Exact Closure Method

The kinetics of the fiber orientation during processing of shortfiber composites governs both the processing characteristics and the cured part performance. The flow kinetics of the polymer melt dictates the fiber orientation kinetics, and in turn the underlying fiber orientation

Estimation of fiber orientation and spin density distribution by diffusion deconvolution

A diffusion deconvolution method is proposed to apply deconvolution to the diffusion orientation distribution function (dODF) and calculate the fiber orientation distribution function (fODF), which is defined as the orientation distribution of the fiber spin density. The dODF can

In vivo investigations of accuracy and precision of fiber orientations in crossing fibers in spherical deconvolution-based HARDI methods

Target audience: Researchers interested in optimizing High-Angular Resolution Diffusion Imaging acquisitions. Introduction: Diffusion MRI methods based on high-angular resolution diffusion imaging (HARDI) acquisitions provide a good trade-off between acquisition time and accuracy
