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 …

This study was undertaken to evaluate the potential of computed ultrasonic tomography for
providing local, quantitative values of an ultrasonic index of attenuation, on the premise that …

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 …

The measurement of tissue attenuation from pulse-echo data has been widely investigated.
This paper examines correction of the measurements for the effect of the transducer beam …

Physical principles underlying the application of the techniques of computed tomography to
quantitative imaging of the ultrasonic attenuation within soft tissue specimens are explored …

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

This paper describes the calculation of absolute ultrasonic attenuation as a function of
frequency by processing backscattered signals obtained from a clinical imaging instrument …

This paper deals with computed imaging techniques for ultrasonic transmission tomography.
Cross-sectional images of the refractive index in soft biological tissues can be obtained by …

In recent years Ultrasonic imaging systems have provided valuable diagnostic information in
the clinical enviroment with no apparent harm to the patient. Much effort has gone into …

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 …
