Tracking of myocardial walls and study of contractility and thickening

R. Casero−Cañas‚ J. Timperley‚ J. A. Noble and H. Becher

Abstract

The study of cardiac muscle contractility is fundamental in the evaluation of cardiac function. We propose a continuous measure of contractility based on segment thickening in echocardiographic contrast B-mode time series. Thickness is computed with the symmetric nearest neighbour distance method from the inner to the outer myocardial walls. Preliminary results from 2 studies are compared to nominal scoring by an expert and illustrate how this measure can be useful in the detection of hypokinetic segments.
