ABSTRACT
Quantitative analysis of cardiac motion is of great clinical
interest in assessing ventricular function. Real-time 3-D
(RT3D) ultrasound transducers provide valuable four-
dimensional information, from which quantitative
measures of cardiac function can be extracted. Previously,
we presented a method based on four-dimensional optical
flow motion estimation for anatomical tracking of
