High-speed measurement of two-dimensional displacement of myocardium using element RF data of ultrasonic probe

Abstract Improving the accuracy of heart wall motion measurement is essential to realise better cardiac function evaluation. This paper proposed a two-dimensional (2D) displacement estimation method with high temporal resolution using 2D complex cross-correlation element RF signals an ultrasonic probe between frames returned from target scatterers. The application phantom confirmed its principle. estimated was consistent set displacement. Subsequently, applied two healthy subjects measure interventricular septum during one cycle. Consequently, systole and diastole, movement myocardium measured, results were validated.
