Quantitative analysis of cardiac motion is of great clinical interest in assessing ventricular function. Real-time 3-D (RT3D) ultrasound transducers provide valuable fourdimensional 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 myocardium in RT3D ultrasound, from which myocardial displacement fields and dynamic cardiac metrics were computed.doi:10.1109/isbi.2007.357009 dblp:conf/isbi/DuanAHL07 fatcat:ncq5wo6hljfc7ppujqfhsv26f4
