March 25, 2026 - Introducing OpenMRF

OpenMRF is now live!

After more than three years of collaborative development, we are excited to share this project with the world on our brand-new website. OpenMRF will facilitate rapid MRF sequence prototyping and enable cross-vendor studies to improve qMRI standardization and reproducibility.

As part of this release, we have moved all code to a new GitHub Organization — please use the openmrf-core-matlab repository there going forward.
