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
developed gr-MRI software package comprises a set of Python scripts, flowgraphs, and
signal generation and recording blocks for GNU Radio, an open-source SDR software
package that is widely used in communications research. gr-MRI implements basic event
sequencing functionality, and tools for system calibrations, multi-radio synchronization, and …
