We describe methods for simultaneously acquiring and subsequently combining data from a
multitude of closely positioned NMR receiving coils. The approach is conceptually similar to …

The fundamental limit for NMR imaging is set by an intrinsic signal‐to‐noise ratio (SNR) for
a particular combination of rf antenna and imaging subjects. The intrinsic SNR is the signal …

Describes a new nuclear magnetic resonance (NMR) imaging technique which the authors
call'spin warp imaging'and gives examples of its application to human whole-body imaging. …

We have developed radiofrequency coils for high-field head and whole-body imaging which
achieve near optimal rf field (Br) homogeneity and signal-to-noise ratio (SNR). The design, …

A comparison of experimental imaging results obtained with linearly polarized and circularly
polarized radiofrequency excitation and reception is presented. Simulation images in good …

A nuclear magnetic resonance (NMR) imaging system signal‐to‐noise calibration technique
based on an NMR projection of distilled water in a cylindrical bottle is proposed. This …

Circular loops are the most common MR detectors. Loop arrays offer improved signal‐to‐noise
ratios (SNRs) and spatial resolution, and enable parallel imaging. As loop size decreases…

Simple theoretical estimates of the average, maximum, and spatial variation of the
radiofrequency power deposition (specific absorption rate) during hydrogen nuclear magnetic …

Gradient acoustic noise has been measured and characterized for an epoxy‐potted, shielded
gradient assembly in a 1.5 T MRI system. Noise levels vary by 10 dB or more as a function …

Solvent-suppression NMR techniques are combined with a pulsed magnetic field gradient
and surface coil detection method of spatial localization. The result is a technique that …
