A framework for testing, validating, and sharing open-source MR sequences was developed to improve their accessibility, repeatability, and safety. Accessibility is improved by requiring documentation of sequence usage and data processing steps, repeatability by requiring test experiments and examples to replicate, and safety by requiring simulation or records of SAR and PNS levels. Forms and guidelines are provided to help developers and users package, share, and apply novel sequences efficiently. The framework was demonstrated for two common sequences, Inversion Recovery Spin Echo (IRSE) and Turbo Spin Echo (SE), and they were packaged and shared in an open-source repository.
