Trap design for insertable second-nuclei radiofrequency coils for magnetic resonance imaging and spectroscopy
TL;DR: In this article, the use of a resonant trap in conjunction with a modular design permitted the insertion of the phosphorus coil as an add-on into multiple existing proton coils, suggesting particular applicability in the high-field arena, where spectroscopy holds great promise.

A 64-Channel Transmitter for Investigating Parallel Transmit MRI
TL;DR: A relatively inexpensive transmit system that can be easily duplicated by users with a reasonable level of RF hardware design experience is described, capable of dynamic modulation necessary for transmit SENSE by replacing the digital potentiometers controlling the vector modulators with commercially available analog output boards.

TL;DR: In this article, a detection surface is defined by a plurality of sensors, each of which is operable to receive image information concerning a particular portion of a target surface by substantially confining to the each of the sensors magnetic flux associated with the particular part of the target surface.

Reducing SAR in parallel excitation using variable-density spirals: a simulation-based study.
TL;DR: Variable-density (VD) spiral trajectories are explored as a means for SAR reduction in parallel-excitation pulse design, and simulation results show that, for the same pulse duration, parallel excitation with VD spirals can achieve a lower SAR compared to CD spirals for parallelexcitation.

Quadrature transmit coil for breast imaging at 7 tesla using forced current excitation for improved homogeneity
Mary P. McDougall,S. Cheshkov,B S Joseph Rispoli,Craig Malloy,Ivan E. Dimitrov,Ivan E. Dimitrov,Steven M. Wright +6 more
TL;DR: To demonstrate the use of forced current excitation (FCE) to create homogeneous excitation of the breast at 7 tesla, insensitive to the effects of asymmetries in the electrical environment.
