Accurate assessment of ventricular function is clinically important. In this abstract, a method for reconstructing three-dimensional biventricular strain over time from unwrapped harmonic phase measurements is validated in normal volunteers and patients. The strain obtained is compared to 3D strain obtained from a feature-based method and 2D strain obtained from harmonic phase strain measurements.
