Variations of the average displacement error along the streamwise direction $\left({\delta }_x\right.$ ) normalized by maximum streamwise particle displacement ( $∆x_{ref}$ ) as a function of the inflow Reynolds number ( $R{e}_{inflow}$ ) in the stenosed LAD phantom. For smart-PIV, the normalized average displacement error ${\delta }_x/∆x_{ref}$ is evaluated also by virtually reducing the image acquisition frequency to 480 Hz (for $R{e}_{inflow}$ = 21).
