Synopsis

Keywords: Data Acquisition, Acquisition Methods, Open Science, Reproducible Research, Open Source, Pulseq

Motivation: Tools for cross-platform open-source pulse sequence development have recently gained substantial traction within the MRI community. An important ingredient thereof is the set of scanner-specific “driver” or “interpreter” software modules, which currently have to be compiled and tested for every scanner model and software version.

Goal(s): Develop an easy to maintain flexible Pulseq interpreter, with a minimal dependency on the scanner software.

Approach: A Pulseq interpreter that relies on the prototype Siemens “Remote Sequence Streaming Interface” was implemented in Python.

Results: Our proof-of-concept implementation shows identical simulated sequence diagrams compared to the previous Pulseq interpreter and is producing similar images on the scanner.

Impact: Interpreter modules are instrumental for executing open pulse sequences on a particular scanner. The presented work paves a way towards reducing the effort associated with their development and maintenance by potentially reducing adaptations and tests for every scanner software version.
