Rapid 3D Spoiled Steady-State Imaging with Yarn-Ball Acquisition

A novel multi-shot 'Yarn-Ball' technique is presented which facilitates efficient 3D k-space sampling through large loops with low acceleration. The differential equations underpinning this technique are described, and the number of trajectories required to fully sampling 3D k-space are compared to standard gradient echo. Unlike gradient echo, trajectory requirements can be dramatically reduced by >100x with readout duration increase. In the context of 3D spoiled steady-state imaging, Yarn-Ball allows the generation of much higher resolution images than is possible with standard gradient echo for the same TR and scan duration.
