This monograph presents a tutorial review of the current state-of-the-art in ultrasonic
attenuation estimation in reflection. Clinical indications which provide the motivation for …

Short-time Fourier analysis is well suited for processing tissue echographic signals which
are nonstationary. We have investigated the use of short-time Fourier analysis to provide an …

This paper describes the image formation in medical ultrasound for the case of scattering
media. The texture statistics are dominated by speckle formation. The effects of spatial, fixed …

Certain diffuse liver diseases, such as hepatitis and cirrhosis, are difficult to diagnose from
the information contained in ultrasound images. A signal processing procedure is described …

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

A study was performed to find and test quantitative methods of analysing echographic
signals for the differentiation of diffuse liver diseases. An on-line data acquisition system was …

The acoustic attenuation coefficient of soft biological tissue has been observed to have an
increasing linear-with-frequency attenuation characteristic with a slope, denoted by β, that …

In vivo quantification of shear-wave attenuation in soft tissues may help to better understand
human tissue rheology and lead to new diagnostic strategies. Attenuation is difficult to …

A method based on broad-band amplitude for obtaining attenuation and echogenicity
estimates from homogeneous phantoms and tissues is described. Although a number of …
