Synopsis

Keywords: Software Tools, Software Tools

Motivation: A community-driven vendor-agnostic, open-source protocols (VOP) framework will expand the acquisition of reproducible MR data by collaboratively, safely, effectively, and ethically sharing magnetic resonance (MR) protocols.

Goal(s): To validate and share two Pypulseq and GammaStar generated pulse sequences at multiple sites and two field strengths

Approach: We acquired T1w, T2w, and quantitative relaxometric data from six sites on the Siemens, Philips, and the mri4all Zeugmatron1 platforms; sharing the code, data, images and documentation; compliant with the framework requisites

Results: The sites fulfilled the requirements of the framework, and sites performing qMR provided similar and accurate T1 and T2 measures on the respective phantoms

Impact: We demonstrated the expanded use of the VOP framework to validate and share the IRSE and TSE sequences across sites, vendors, software versions, and two field strengths. This framework created an online platform to interact and share pulse sequences.
