Correlation and bias for the velocity at peak filling, automatic tracking compared to manual measurements. Scatter plot of the peak filling velocity in cm/s (left panel) and Bland-Altman plot of peak filling velocity in cm/s (right panel) for the automatic tracking against manual measurements in n = 20 subjects. Top row shows results for the left ventricle and the bottom row shows the results for the right ventricle. The identity line is shown as a solid line in the scatter plots, and linear regression as a dashed line. In the Bland-Altman plots the mean bias is shown as a solid line with limits of agreement (±2SD) as dashed lines. Correlation R value was 0.74 for the left ventricle, and 0.85 for the right ventricle. For the left ventricle, mean bias was 23.0 cm/s with limits of agreement between −17.0 and 63.0 cm/s. For the right ventricle, mean bias was 10.8 cm/s with limits of agreement between −18.2 and 39.8 cm/s
