Table 3 Signal-to-error ratio (in dB) between the in vivo experiment results from each of the three CFD approaches—pure CFD (labeled “CFD”); CFD driven by one PC-MRI velocity component (labeled “CFD + 1D”); and CFD driven by all three PC-MRI velocity components (labeled “CFD + 3D”), relative to the MRI-measured velocity field
