RÉSUMÉ

Myocardial infarction is one of the leading causes of death in the United States. The currently available techniques for diagnosis are accurate enough but suffer from certain drawbacks such as accurate quantitative measure of severity, extent and precise location of the infarction. Since the acoustic properties in the damaged region are usually changing, one can study them by the use of ultrasound.
Ultrasound backscatter measurements have been the main vehicle of noninvasive myocardial tissue characterization [1-5] and myocardial infarction [6-8] for many years. Yet these studies show a lot of variability in the results, one of the main reasons being the human factor. Observed alterations are attributed to changes in tissue water content or increase in deposition of collagen, but the exact factors causing the acoustic changes are not completely understood yet.
