MR sequence development is either based on complex, platform-specific solutions or restricted by fixed sequence structures together with a strict hierarchical implementation of loops. This abstract introduces event-based traversing of gammaSTAR sequences together with a buffered real-time execution at the scanner. The concept provides easy implementation of arbitrary, interleaved loop structures as well as memory efficient, real-time capable sequence execution in a vendor-agnostic environment. It is demonstrated for interleaved loop structures in a pCASL 3D GRASE sequence for brain perfusion imaging.
