Fast diffusion imaging with high angular resolution. [PDF]
Magn Reson Med, 2017 PurposeHigh angular resolution diffusion imaging (HARDI) is a well‐established method to help reveal the architecture of nerve bundles, but long scan times and geometric distortions inherent to echo planar imaging (EPI) have limited its integration into clinical protocols.MethodsA fast imaging method is proposed here that combines accelerated multishot

High angular resolution diffusion-weighted imaging in mild traumatic brain injury [PDF]
NeuroImage: Clinical, 2017 We sought to investigate white matter abnormalities in mild traumatic brain injury (mTBI) using diffusion-weighted magnetic resonance imaging (DW-MRI). We applied a global approach based on tract-based spatial statistics skeleton as well as constrained ...

Texture tomography with high angular resolution utilizing sparsity. [PDF]
J Appl CrystallogrWe demonstrate an approach to the reconstruction of scanning probe X-ray diffraction tomography data with anisotropic polycrystalline samples. The method involves reconstructing a voxel map containing an orientation distribution function in each voxel of a bulk 3D sample.

Converting Multi-shell and Diffusion Spectrum Imaging to High Angular Resolution Diffusion Imaging [PDF]
Frontiers in Neuroscience, 2016 Multi-shell and diffusion spectrum imaging (DSI) are becoming increasingly popular methods of acquiring diffusion MRI data in a research context. However, single-shell acquisitions, such as diffusion tensor imaging (DTI) and high angular resolution ...

High-angular-resolution interferometric backscatter meter
Optics Letters, 2022 Backscatter limits many interferometric measurements, including gravitational wave detectors, by creating spurious interference. We describe an experimental method to directly and quantitatively measure the backscatter interference. We derive and verify experimentally a relation between backscatter interference, beam radius, and the scattering sample ...

Gamma Cas Stars as Be+White Dwarf Binary Systems
The Astrophysical Journal Letters, 2022 The origin of the bright and hard X-ray emission flux among the γ Cas subgroup of B-emission line (Be) stars may be caused by gas accretion onto an orbiting white dwarf (WD) companion.

Investigating close binary supermassive black holes at high angular resolution [PDF]
Serbian Astronomical Journal, 2021 Gravitational waves (GW) in the nano-Hz domain are expected to be radiated by close-binaries of supermassive black holes (CB-SMBHs; components bound in a Keplerian binary at mutual distance less than ~ 0.1 pc), which are relicts of galaxy ...
