An automatic method using tissue Doppler for detecting and tracking left ventricular landmarks was robust and yielded measurements comparable to manual selection by four cardiologists.
We introduce a method for automatic detection and tracking of the apex and two landmarks defining the atrioventricular plane in apical views of the left ventricle. The method is based on using tissue Doppler to track a set of candidate points in a cardiac cycle. Each candidate point is given a score based on the gray-scale, the velocity, and the depth profiles. The landmarks with the lowest costs are selected, and measurements are calculated automatically. The method is evaluated by comparing with manual selection by four cardiologists, and the presented results show that the method is robust and extracted measurements are comparable with manual selection.
Torp et al. (Tue,) conducted a other in Echocardiography. Automatic detection and tracking method using tissue Doppler vs. Manual selection by cardiologists was evaluated on Comparability of extracted measurements. An automatic method using tissue Doppler for detecting and tracking left ventricular landmarks was robust and yielded measurements comparable to manual selection by four cardiologists.
