Velocity maps for the individual velocity components (u, v, and w), for an axial slice at the bifurcation of the carotid flow phantom: a PC-MRI; b PC-MRI with added Gaussian noise (\(\sigma =8\) cm/s); c pure CFD solution using noisy PC-MRI data as inlet and oulet velocities; d CFD guided by the noisy PC-MRI data, with \(\lambda =5\times 10^{-9}\); e CFD guided by the noisy PC-MRI data, with \(\lambda =5\times 10^{-8}\); f CFD guided by the noisy PC-MRI data, with \(\lambda =5\times 10^{-7}\); g CFD guided by the noisy PC-MRI data, with \(\lambda =5\times 10^{-6}\)
