The goal of this work is to develop software that enables the rapid implementation of custom
MRI spectrometers using commercially-available software defined radios (SDRs). The …

Abstract Transmit Array Spatial Encoding (TRASE) is a promising new MR encoding method
that uses transmit RF (B 1+) phase gradients over the field-of-view to perform Fourier spatial …

Magnetic resonance imaging (MRI) is a powerful noninvasive diagnostic tool with superior
soft tissue contrast. However, access to MRI is limited since current systems depend on …

Since recovery time of the RF coil is long at low field MRI, the rising and the ring-down times
of the square pulse are also long, which means the applied sinc pulse can easily be …

RF encoding using the Bloch-Siegert shift has the potential to replace conventional gradient
encoding with cheaper RF gradients, and can directly replace gradient pulsing in common …

A gradient-free, Bloch-Siegert effect based nonlinear spatial encoding scheme was
introduced for silent scanning and to eliminate gradient-induced eddy currents in …

Described here are systems and methods for performing magnetic resonance imaging
(“MRI”) using radio frequency (“RF”) phase gradients to provide spatial encoding of …

In this work, we designed a frequency division duplex RF system for frequency encoding
using Bloch-Siegert shift at very low field, with a modification of dual-band pass filters …

To achieve frequency encoding using Bloch-Siegert shift, the off-resonance pulse and signal
reception would need to take place simultaneously. In this work we describe two methods to …
