Fig. 8From: Blood speckle imaging compared with conventional Doppler ultrasound for transvalvular pressure drop estimation in an aortic flow phantomBland–Altman plots illustrating the agreement between A Doppler vs. ground-truth and B BSI vs. ground-truth pressure drop estimations (n = 16). The solid line represents the bias between the 2 methods, while the 95% limits of agreement (± 1.96 standard deviation) are represented by the dashed linesBack to article page
