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

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 …

Comparisons of literature values of attenuation and absorption can yield ratios of 2: l or
greater for soft tissues such as liver. This could imply a major contribution of longitudinal …

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

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 …

An integral expression is derived for the normalization of ultrasonic scattering data to obtain
an average differential scattering cross section per unit volume for tissue which is modeled …

Ultrasonic attenuation measurements may have clinical significance in evaluating the
physiological state of bone tissue. Attenuation of shear and longitudinal waves has been …

This chapter reviews some of the recent advances in the estimation of the local and the total
attenuation, with an emphasis on reducing the bias and variance of the estimates. A special …

Pulse reflection techniques may be used for in vivo measurement of attenuation and
velocity. Measurement of the two-dimensional distribution of pulse attenuation may be …

In this paper we will discuss the measurement of attenuation of soft tissues using broadband
pulsed ultrasound. While all the methods presented here may be used for measuring the …
