The objective of this work was to demonstrate the integration of two open-source MRI software packages: GrOpt and Pulseq. GrOpt allows for robust and fast optimization of gradient waveforms subject to various constraints, while Pulseq allows a flexible and straightforward approach to writing sequences and executing them on a scanner. We demonstrate example pulse sequences that integrate both software packages and show an imaging example from a PC-MRI experiment. The combination of GrOpt and Pulseq allows for optimized arbitrary gradient waveforms to be easily prototyped and run on a scanner.
