Abstract

Quantitative motion analysis of the right ventricle (RV) is important to study its function. However, the RV study is more difficult than that of left ventricle (LV) because of its complex shape and the limitations of the existing imaging methods. We propose a diffeomorphic motion estimation method and apply it to the 3D echocardiography of five open-chest pigs under different steady states. We first validate the motion estimation method by using sonomicrometry. Then we estimate the myocardium strain of different steady states. The RV free wall (RVFW) is divided into twelve segments and their strain patterns in each steady states together with the corresponding cardiac mechanics are analyzed. This is the first time to quantitatively analyze the RVFW segment strains from 3D echocardiography by using algorithm.
