چکیده
Synopsis We describe a model-free method to quantify the spectrum of water mobilities in �xed and live brain tissues. We eliminate confounds caused by anisotropic di៛�usion in brain tissues by measuring orientationally-averaged di៛�usion weighted images over a large range of b-values. Spectra of orientationally-averaged water di៛�usivities show clear distinctions between white matter, gray matter and cerebrospinal �uid, and could provide new biologically-speci�c clinical markers for studying and diagnosing ischemic stroke, tumors, and neurodegenerative disorders and diseases, including in�ammation.

Optical di usion of cw, pulse and density waves in scattering media and comparisons with radiative transfer
Transport theory's equation of transfer is a well-accepted model for wave scattering in a random medium. However, exact solutions are only available for a small class of special cases (isotropic scattering in in nite and semiin nite domains) and thus, analytic solutions for a wide variety of geometries and range of parameters which correspond to more physically relevant situations still remain ...
متن کاملDiffusion Directions Imaging (DDI)
Di usion magnetic resonance imaging (dMRI) is the reference in vivo modality to study the connectivity of the brain white matter. Images obtained through dMRI are indeed related to the probability density function (pdf) of displacement of water molecules subject to restricted di usion in the brain white matter. The knowledge of this di usion pdf is therefore of primary importance. Several metho...
متن کاملDirection Diiusion
In a number of disciplines, directional data provides a fundamental source of information. A novel framework for isotropic and anisotropic di usion of directions is presented in this paper. The framework can be applied both to regularize directional data and to obtain multiscale representations of it. The basic idea is to apply and extend results from the theory of harmonic maps in liquid cryst...
متن کاملCombining Curvature Motion and Edge-Preserving Denoising
In this paper we investigate a family of partial di erential equations (PDEs) for image processing which can be regarded as isotropic nonlinear di usion with an additional factor on the right-hand side. The one-dimensional analogues to this lter class have been motivated as scaling limits of one-dimensional adaptive averaging schemes. In 2-D, mean curvature motion is one of the most prominent e...
متن کاملOnline orientation distribution function reconstruction in constant solid angle and its application to motion detection in high angular resolution diffusion imaging
The di usion orientation distribution function (ODF) can be reconstructed from q-ball imaging (QBI) to map the complex intravoxel structure of water di usion. As acquisition time is particularly large for high angular resolution di usion imaging (HARDI), fast estimation algorithms have recently been proposed, as an on-line feedback on the reconstruction accuracy. Thus the acquisition could be s...
