Fig. 4

PC-MRI measurements in vessel phantom with inner diameter 2.2 mm and with different acquisition parameters. The flow rate velocities were binned according to the radial distance from the tube center. The plot shows the mean and standard deviation calculated over all phases and repetitions. The velocity scale for individual acquisition parameters is shown separately. Gray horizontal lines represent 0 cm/s for each acquisition parameter, with the first gray line at the bottom pertaining to the baseline setting.
