Using a one-dimensional model of wave propagation, the ultrasonic attenuation can be
estimimated from spectral analysis of RF A-scans. The results of computer modeling studies …

Previous reports have shown that the variance in ultrasound attenuation measurements is
reduced when spatial and frequency compounding were applied in data acquisition and …

Diffraction effects are a cause of error when estimating the frequency dependent attenuation
of ultrasound in biological tissues in the reflection mode. Comparison of attenuation values …

Various means of characterizing ultrasonic attenuation in tissue are reviewed. A simple
method for estimating frequency-dependent attenuation via measurement of the zero …

The accuracy of the spectral difference method for measuring ultrasonic attenuation has
