Reduction of lift-off effects for pulsed eddy current NDT
The lift-off effect is commonly known to be one of the main obstacles for effective eddy current NDT testing as it can easily mask defect signals.

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T
ABSTRACT PurposeTo enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. MethodsThe custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore ...

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.

The Oceanic Eddy Heat Transport
The rectified eddy heat transport is calculated from a global high resolution ocean general circulation model. The eddy heat transport is found to be strong in the western boundary currents, the Antarctic Circumpolar Current, and the equatorial region ...

ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

We investigated associations between a panel of diffusion MRI metrics and myelin content, using ViSTa apparent myelin water fraction (aMWF) as a proxy for myelin. Fractional anisotropy (FA) showed a robust association with aMWF; however, more advanced metrics including radial kurtosis (K⊥) and axonal water fraction (f) had stronger correlations ...
