From: A novel approach to phase-contrast velocity offset correction by in vivo high-SNR acquisitions

Figure 2

Mean residual velocity error after correction, absolute values averaged across all 18 flow studies as a function of the polynomial order and pixel acceptance % (λ) used for the surface fit, using (a) the original pulse sequence and (b) the new high-SNR pulse sequence acquired aiming for higher fitting accuracy (note: not for flow measurement). Residual errors above 1.8cm/s have been removed from both plots for clarity.
