Real-time 3D ultrasound has become a promising new tool for diagnostic and
interventional cardiac procedures. In particular, full volume analysis of cardiac structures
is now possible because of ultrasound's high tissue/blood contrast and a temporal
resolution capable of capturing fast-moving cardiac structures. The temporal resolution
of three-dimensional ultrasound is particularly attractive because it captures the
movement characteristics of highly dynamic structures within the heart. Our results aim
to fully characterize the four-dimensional (3D + time) movement of the mitral valve for
better understanding of its behavior prior to surgical interventions, such as mitral valve
