a) Schematic illustration showing the method of establishing a relationship between the magnitude of cyclic variation and the overall myocardial backscatter level by keeping the respective systolic and diastolic intracellular acoustic impedances the same while systematically increasing the extracellular acoustic impedance (keeping the systolic and diastolic values of the extracellular acoustic impedance equal). b) Predicted relationship between the magnitude of cyclic variation and the overall myocardial backscatter level.
