TOPPE and Pulseq are two examples of open-source, vendor-agnostic frameworks for rapid prototyping and implementation of MR sequences. Both have demonstrated their ability to easily execute a variety of highly specific and customized sequences on different vendors. Cross-vendor translation of sequences generated by these two frameworks can enable multi-site and multi-vendor evaluation of a single sequence implementation. This study demonstrates this capability by porting a spiral-based fMRI sequence implemented in TOPPE on one vendor platform to Pulseq to run on another vendor. Results show comparable in vivo SNR and image contrast for Pulseq and TOPPE implementations.
