Real-time three-dimensional (RT3D) ultrasound with matrix-phased array transducers enable fast, non-invasive visualization of cardiac ventricles. Segmentation of ventricular volumes on RT3D ultrasound is typically performed at end-diastole (ED) and end-systole (ES). Automation of the segmentation process and propagation of segmentation in time is challenging. In this context, a correlation-based 3D+Time optical flow algorithm was applied for tracking of myocardial surfaces. Initialization was performed with either manual tracing or QLAB© software (Philips Medical Systems).
