Eddy current artifacts in hybrid-state sequences could be minimized temporally reordering the radial spokes with a simulated annealing based algorithm.
Reconstructed coefficient images for each of the 6 HSFP experiments. The trajectories used for the images (i,ii,iii) are not reordered, whereas those used for (iv,v,vi) are reordered. From the analysis in Fig.2 we expect the images (ii,iii) be severely impacted by eddy currents.
Representative nonlinear least-square fit results based on the coefficient images in Fig. 3 ii (top row) and v (bottom row).
