For pt. I see ibid., vol. 35, no. 2, p. 242 (1988). To determine the relative contributions of
ultrasonic loss mechanisms in tissues, independent measurements of total attenuation and …

Error estimation for pulse decay absorption and radiation force insertion loss attenuation
measurements are developed. In absorption measurements, significant difficulty lies with …

Ultrasonic loss mechanisms which arise from the microscopically inhomogeneous nature of
soft tissue are investigated over the frequency range 1 to 10 MHz. Contributions to the …

This chapter contains sections titled: Introduction Tissue–Ultrasound Interaction Cross‐
Sections Theory of Mechanisms for the Absorption of Ultrasonic Longitudinal Waves …

Various means of characterizing ultrasonic attenuation in tissue are reviewed. A simple
method for estimating frequency-dependent attenuation via measurement of the zero …

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 …

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

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

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 …

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 …
