We present a simple MR pulse programming framework for rapid prototyping of complex, custom MR pulse sequences. We define a file format that contains all low-level details of an MR imaging experiment, along with a driver (or interpreter) that loads the file(s) and executes the experiment on a General Electric scanner. We demonstrate that a wide range of sequences can be implemented with this setup, subject to limitations such as non-overlapping waveforms. Our framework is conceptually similar to Pulseq, a recently-introduced file format specification for which drivers for other vendor platforms exist (at present, Siemens and Bruker).
