This work develops an end to end, open source, vendor neutral package that allows for fast prototyping of magnetic resonance fingerprinting using Pulseq. In this work, a previously published sequence was implemented in Pulseq, and data were acquired on ISMRM/NIST phantom. The raw data were reconstructed and matched with an extended phase graph simulated dictionary. Automated region of interest analysis was performed to extract T1 and T2 estimation for each sphere of the phantom. The results show that T1 and T2 estimations for 17 spheres of T1 and T2 arrays are within 20% of gold standard measurements.
