Synopsis

Keywords: Software Tools, Software Tools, open-sourceWe demonstrate quantitative T1 and T2 mapping tools, built from open-source components Pulseq and qMRLab, suitable for multi-center multi-platform studies. The end-to-end solution includes acquisition, reconstruction, ROI analysis, and repeatability testing. The tools are demonstrated in the context of 0.55T relaxometry at two different sites and three scanners with two different hardware and software specifications. Relaxometry results are validated against results derived from vendor-provided sequences.
