The default MRI scanner systems are not equipped with key technical resources for rapid deployment of novel non-Cartesian pulse sequence approaches. Here, we describe a Graphical Programming Interface-based (GPI) platform that is further embedded into the vendor reconstruction environment. This allows for comprehensive development and validation of new trajectories by integrating on-line MRI systems development with off-line resources such as MATLAB, which also enhances trainee-driven research efforts. This tool offers a set of resources including real-time display of MRI k-space and prototyping/characterization of sampling trajectory corrections that may simplify and streamline these non-Cartesian designs.
