The accuracy of the spectral difference method for measuring ultrasonic attenuation has
been investigated using tissue-mimicking phantoms. Attenuation coefficients of the phantom …

The measurement of tissue attenuation from pulse-echo data has been widely investigated.
This paper examines correction of the measurements for the effect of the transducer beam …

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

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 …

Attenuation measurements of various tissue minicking phantoms and three different groups

A frequency domain signal processing scheme is developed for measuring attenuation and
attenuation slope in vivo, using equally spaced depth samples and linear regression …

Global and local attenuation coefficient estimates were calculated using three methods: the
envelope peak method, the central-frequency-downshift method, and the zero-crossing …

In a study involving 10 different sites, independent results of measurements of ultrasonic
