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 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 …

Backscattered ultrasonic waveforms from selected regions of the liver were collected from B-
scans of 11 male patients ranging from 13 to 41 years of age and analyzed to determine …

A known method for the determination of the attenuation coefficient of tissues involves the
measurement of the center frequency downshift of Gaussian spectra. The tissue is generally …

A spectroscopic method of measuring attenuation is described and measurements of
attenuation as a continuous function of frequency between 1· 0 and 7· 5 MHz presented for …

In the field of biological tissue characterization, fundamental acoustic attenuation properties
have been demonstrated to have diagnostic importance. Attenuation caused by scattering …

The acoustic attenuation coefficient of most soft biological tissues has an approximately
linear-with-frequency attenuation characteristic. The slope of the attenuation coefficient with …

The propagation of ultrasound pulses in inhomogeneous media is described, and it is
shown that they are scattered by fluctuations in density and compressibility. It is proposed …

A method has been developed for the absolute determination of the backscattering
coefficient of ultrasound by soft mammalian tissues. An expression is derived for the …

In this paper we show that one can measure integrated attenuation for a soft-tissue structure
simply by measuring the center frequencies of the incident and transmitted pulses. Except …
