The effect of temperature and thermal dose (equivalent minutes at 43° C) on ultrasonic
attenuation in fresh dog muscle, liver, and kidney in vitro, was studied over a temperature …

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

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 …

In spite of extensive applications of ultrasound in diagnosis, therapy and even surgery, there
are still many problems to be solved in the basic physics of sound propagation in tissues …

A set of test samples, all containing ultrasonically equivalent tissue‐mimicking material, was
produced and measurements of ultrasonic speed and ultrasonic attenuation coefficients …

The study described herein was undertaken to determine the role of proteins, in general,
and collagen, in particular, in the observed absorption and speed of ultrasound in biological …

Ultrasonic attenuation and backscattering coefficients and speed of sound were determined
experimentally, as functions of frequency, in samples of fresh mammalian brain, liver and …

There exists a large body of in vitro experimental data on ultrasonic scattering from various
biological tissues in the literature. 1-9 It would be extremely difficult, if not impossible, to do …
