2P2-F22 Noninvasive Sensing of Ventricular Stiffness

Abstract

This paper discusses a concept of a noninvasive sensing method that can estimate a left ventricular stiffness towards a medical diagnosis. Focusing on not only the strain of ventricular wall but also the displacements of epicardium during diastole of heart beat, we introduce an index of ventricular stiffness based on a two-layer elastic model. Applying the proposed method to the echocardiography, we show an example where we can estimate the difference between soft and hard ventricular walls.
