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

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 …

This report addresses the potential of reconstructions based on quantitative indices of
ultrasonic attenuation for characterizing the state of soft tissue. Emphasis is on those aspects …

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 …

A method that combines both spatial and frequency compounding is described for
measuring attenuation in tissue. The technique applies a reference phantom to account for …

We examine the consequences of anisotropy in the ultrasonic attenuation on computed
tomography. A phenomenological model for anisotropy in the ultrasonic attenuation of soft …

The nonionizing and noninvasive characteristics of ultrasonics promote its increasing use in
medical applications. Computerized ultrasonic attenuation tomography is one area where …

Previous reports have shown that the variance in ultrasound attenuation measurements is
reduced when spatial and frequency compounding were applied in data acquisition and …
