In this work, we investigate the influence of eddy currents on hybrid state free precession (HSFP) sequences with 3D radial (koosh-ball) readout trajectories and propose a simulated annealing-based algorithm to minimize their impact.

The proposed approach of reordering the temporal succession of radial spokes successfully minimized the influence of eddy currents on HSFP experiments. Although these results were shown in the context of a HSFP experiment, we believe that this approach could find a broader application in multi-shot bSSFP sequences.
