Synopsis

Keywords: New Trajectories & Spatial Encoding Methods, Pulse Sequence Design, SPEN, open-source

Motivation: SPEN is an alternative encoding method with various advantages. However, SPEN sequences are not easily accessible.

Goal(s): The aim of this project is to make SPEN in the open-source framework Pulseq openly available. This enables reproducibility and availability of SPEN.

Approach: The SPEN sequence was developed in MATLAB using the Pulseq framework and is openly accessible via a GitHub repository. In addition, a sequence example is developed as a guide for the use of SPEN.

Results: A SPEN sequence is openly available for the vendor-independent execution on different platforms.

Impact: The implementation in Pulseq significantly increases the accessibility of SPEN. This hopefully leads to more SPEN-related studies and to a more widespread use in clinical applications.
