INTRODUCTION: Diffusion tensor MRI (DT-MRI) has been useful in estimating microscopic changes in tissue based on water molecular diffusion. However, DT-MRI is inappropriate in regions with non-parallel fibers [1]. To overcome this, high angular resolution diffusion (HARD) encoding schemes have been proposed [2] and used for finite mixture of Gaussians [2], q-Ball imaging [3] and spherical decon...

Abstract We describe an algorithm for generating fiber-filled volume elements use in computational homogenization schemes. The permits to prescribe both a length distribution and fiber-orientation tensor of second order, composites with industrial filler fraction can be generated. Typically, short-fiber composites, data on the fiber-length volume-weighted order is available. consider model wher...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...

Ever since the introduction of the concept of fiber tractography, methods to generate better and more plausible tractograms have become available. Many modern methods can handle complex fiber architecture and take on a probabilistic approach to account for different sources of uncertainty. The resulting tractogram from any such method typically represents a finite random sample from a complex d...

This paper presents a novel tractography algorithm for more accurate reconstruction of fiber trajectories in low SNR diffusion-weighted images, such as neonatal scans. We leverage information from a later-time-point longitudinal scan to obtain more reliable estimates of local fiber orientations. Specifically, we determine the orientation posterior probability at each voxel location by utilizing...
