Software defined radios have been shown to be a highly configurable, low cost alternative to traditional MRI spectrometers. They are well supported by the open-source GNU Radio software, however there are currently no GNURadio extensions to enable their use for MRI. In this work we describe a library of GNU Radio extensions for MRI, which implements all of the basic capabilities of an MR spectrometer in an SDR. The software will enable users to develop custom, low-cost MR spectrometer systems without requiring custom hardware design. We demonstrate its use via its built-in spin echo, gradient echo, and inversion recovery sequences.
