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 …

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 …

In a study involving 10 different sites, independent results of measurements of ultrasonic
properties on equivalent tissue‐mimicking samples are reported and compared. The …

The substitution method of measuring scattering was developed initially as a means of
overcoming the problem of attaining acceptable accuracy when very many system …

Studies conducted in this laboratory to explore the feasibility of utilizing acoustic impedance,
attenuation, and scattering characteristics of tissues for enhancing the diagnostic …

The dearth of information on the physical processes involved in the propagation of
ultrasound in tissue and the growing need for such information are discussed. The physical …

Quantitative backscattering measurements have been made using the substitution method
used to measure the scattering properties of blood previously. We have obtained preliminary …

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 …

Propagation relations for compressional waves in isotropic, elastic media are described
briefly and discussed with reference to ultrasonic propagation in biological structures. A …

In this paper, a closed‐form expression is derived for the absorption of ultrasound by
biological tissues. In this expression, the viscothermal and viscoelastic theories of relaxation …
