Purpose The SNR at the center of a spherical phantom of known electrical properties was
measured in quasi‐identical experimental conditions as a function of magnetic field strength …

Purpose A 128‐channel receive‐only array for brain imaging at 7 T was simulated,
designed, constructed, and tested within a high‐performance head gradient designed for …

Purpose We examined magnetic field dependent SNR gains and ability to capture them with
multichannel receive arrays for human head imaging in going from 7 T, the most commonly …

Objective: We propose a framework to interpret the effects of High Permittivity Materials
(HPM) on the performance of radiofrequency coils in Magnetic Resonance Imaging (MRI) …

In this work, we introduce a theoretical framework to describe the scattering from spheres. In
our proposed framework, the total field in the outer medium is decomposed in terms of …

Transmit efficiency specifies the amplitude of the magnetic resonance excitation field
produced over a region of interest with respect to the radiofrequency (RF) power deposited …

Purpose Toward pushing the boundaries of ultrahigh fields for human brain imaging, we
wish to evaluate experimentally achievable SNR relative to ultimate intrinsic SNR (uiSNR) at …

Purpose We model the performance of parallel transmission (pTx) arrays with 8, 16, 24, and
32 channels and varying loop sizes built on a close‐fitting helmet for brain imaging at 7 T …

We investigated how to construct low-order subspace basis sets to accurately represent
electromagnetic (EM) fields generated within inhomogeneous arbitrary objects by radio …

Purpose Recent numerical and empirical results proved that high permittivity materials
(HPM) used in pads placed near the subject or directly integrated with coils can increase the …
