Figure 6From: Volume quantification by contrast-enhanced ultrasound: an in-vitro comparison with true volumes and thermodilution Bland-Altman plots showing the agreement between measured volumes by contrast enhanced ultrasound and true volume of the set-up. The volumes measured with contrast enhanced ultrasound are displayed in left and right panel, using the LDRW double fit (DF) method and LDRW impulse response (IR) method, respectively. The bold line indicates the mean difference between CEUS measured and true volumes (bias), the dashed lines indicate two times the standard deviation.Back to article page
