Abstract
Ultrasonic cardiac tissue characterization on the basis of signal-speed and signal-attenuation measurements is covered with problems [1]. It has been evaluated, however, that the frequency dependence of the attenuation coefficient is different in normal and infarcted myocardium [1]. Joynt et al have shown that the histogram of echo amplitude distribution taken from A-scans is shifted and broadened in damaged myocardium [3]. These findings are obtained by applying Fourier transformation, spectral analysis and other methods well known in the field of system theory.
