A major challenge for researchers in designing new pulse sequences is the limitation of needing to know vendor-specific programming environment. The Pulseq tool in Matlab has overcome this issue. This work demonstrates an open source implementation of Pulseq in GPI Lab to further access to Pulseq. Also, this enables a single platform on GPI to integrate the PSD with the rest of the MR research pipeline: simulation, reconstruction, image analysis and visualization. The Pulseq-GPI implementation is demonstrated through a gradient recalled echo. It is capable of designing all sequences/enhancements that Pulseq currently offers.
