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 …

Soft biological tissue has been observed to exhibit an acoustic attenuation log-magnitude
characteristic which increases as an approximately linear function of frequency. This paper …

Ultrasonic attenuation and backscattering were measured for bovine brain, spleen and liver
and for porcine iiver as a function of time after excision for times up to 120 hr. The …

A practical ultrasound system is described which is capable of making measurements of
attenuation and velocity in tissue as a function of frequency. This method is based upon a …

Most ultrasonic diagnostic equipment are based on the observation of the waves scattered
by tissues. Although these instruments generally perform useful clinical diagnosis, they do …

Although the dispersion of tissue is small and difficult to measure, it can be calculated from a
knowledge of the tissue's attenuation. A minimum-phase function, which characterizes tissue …

The attenuation of an ultrasound pulse within tissue can be estimated from either the
amplitude decay or the frequency downshift of returning echoes. The authors compare the …

The fundamental role of the assumption of plane wave ultrasonic propagation in attenuation
and scattering measurements on soft tissues is discussed. The evidence for and against the …

Estimations of scattering parameters, such as average scatterer diameter, from rf signals
backscattered from random media (tissues) are made from the frequency dependence of the …
