Shape-Constraint Elastic Link Model for Myocardial Motion Tracking in Echocardiogram

抄録

We propose a novel technique to track the motion of the left ventricular myocardium in B-mode scan of ultrasonic RF signals. The proposed method is generally based on the traditional correlation based motion tracking, and then we introduce a new objective function to be optimized into the method. In our method, the objective function is defined from the model where multiple Regions of Interest (ROIs) are connected to each other with elastic links. The elastic links reflect both elastic and shape properties of myocardium. The proposed method is implemented and evaluated using three clinical subjects. The results show that the tracking accuracy of the proposed method is higher than that of the conventional method.
