ultrasonic tissue characterization based on measurement of the
frequency dependence of ultrasonic backscatter.

AB : Quantitative myocardial tissue characterization is being developed to
complement and expand conventional echocardiography by delineating
the physical state of myocardium under diverse pathophysiologic
conditions. Real-time quantitative integrated backscatter imaging has
already been applied to patients with ischemic heart disease,
hypertrophic cardiomyopathy, and cardiac allograft rejection in
clinical investigations performed in the United States, Europe,}
and Japan.
