Space-Varying Coefficient Models for Diffusion Tensor Imaging using 3d Wavelets [PDF]
, 2006 In this paper, the space-varying coefficients model on the basis of B-splines (Heim et al., (2006)) is adapted to wavelet basis functions and re-examined using artificial and real data. For an introduction to diffusion tensor imaging refer to Heim et al.

The Egyptian Journal of Radiology and Nuclear Medicine, 2019 Background Conventional MRI provides important morphologic information regarding the brain and spinal cord involvement by demyelinating plaques. However, it is of almost no value in assessing the normal-appearing white matter which has been proved by ...

Advanced Functional Materials, EarlyView.The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Diffusion-Weighted Imaging and Diffusion Tensor Imaging [PDF]
Current Radiology Reports, 2014 Assessment of the integrity of the articular cartilage is considered key for the early diagnosis of osteoarthritis (OA). Diffusion-weighted imaging and diffusion tensor imaging have potential as biomarkers for cartilage composition and structure. The value of diffusion to detect compositional and structural changes in the cartilage matrix has been ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Characterization of imaging gradients in diffusion tensor imaging [PDF]
Journal of Magnetic Resonance, 2010 For obtaining a complete model the diffusion tensor imaging (DTI) method is derived in a new linear algebraic framework in order to include the effect of all of the magnetic field gradients on the MRI signal. In the framework, the coefficient matrix of the estimation equations consists of the sum of three matrices corresponding to diffusion gradients ...

Advanced Functional Materials, EarlyView.Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...
