From: Divergence-free reconstruction for accelerated 3D phase-contrast flow measurements
Average divergence over the aorta of 5 healthy volunteers for standard and divergence-free reconstruction of fully sampled, 2x and 4x TSENSE data (A) and fully sampled, 2x and 8x k-t PCA data (D). Average error in maximum velocity for standard and divergence-free reconstruction of fully sampled, 2x and 4x TSENSE data (B) and fully sampled, 2x and 8x k-t PCA data (E). In-plane flow pattern in the ascending aorta of one volunteer for fully sampled, 2x and 4x TSENSE (C) and fully sampled, 2x and 8x k-t PCA (F) before and after divergence-free reconstruction.
