given Riverside Research Institute medium as compared to the amount of power that would …

Attenuation is an important parameter in the description prehensions of the physical and
computational foundations of the propagation of an ultrasonic pulse in tissue. Since …

The purpose of this work was to explore the mechanisms which are responsible for the
scattering of ultrasound from skeletal muscle tissue. It was undertaken in response to an …

Attenuation measurements were performed on the quadriceps femoris muscle of 10 normal
volunteers. The measurements were made using a statistical narrowband pulse echo …

The difference between literature values of ultrasonic attenuation and absorption
coefficients, defmed as the scatter coefficient, was related to percent wet weight collagen …

Ultrasonic attenuation coefficients were measured in mammalian liver for frequencies
ranging from 0.5 to 10 MHz and for a range of sample preparations. Certain preparative …

Attenuation and propagation speed in the 1‐to 5‐MHz frequency range were measured in
vitro in 22 tissue samples from six anatomic sites in five normal human brains obtained …

A viscous mechanism for the absorption of ultrasonic energy in tissue is considered. It is
shown that the viscous forces acting between a suitably chosen distribution of suspended …

The purpose of this communication is to report the results of acoustic-attenuation
measurements in mam-malian kidney tissue at frequencies up to 222 MHz and to comment …
