Abstract :
The usefulness of measuring integrated backscatter in diagnosing ischemic heart disease remains to be determined due to the adverse effect of tissue attenuation on measurement accuracy. The measurement of the absolute value of integrated backscatter using as a reference the backscatter power from blood flow near the region of interest is discussed. The method eliminates the adaptive interval clutter component, enabling one to accurately calculate the backscatter power from the Doppler spectrum
