Abstract
Cardiac disease remains a major killer in the world. Improving the management of cardiovascular disease is one of the greatest challenges facing healthcare. It is valuable to study the electro-mechanics of the heart as any asynchrony of electrical activation and disorder of the mechanical properties can lead to abnormalities in heart function. Accurate quantitative of heart motion and deformation are of importance for evaluating normal and abnormal cardiac physiology and mechanics. However, the complexity of LV motion, the absence of internal landmarks in the myocardium and the influence of the right ventricle (RV) on the LV imply that the true motion trajectories of tissue elements are difficult to obtain from image analysis. In this paper we decided to compare two methods of heart motion estimation and consider the advantages or disadvantages of each method.
