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

Most methods for in vivo quantitation of ultrasound attenuation and backscatter are not
available clinically because they rely upon acquiring and analyzing radio frequency (rf) echo …

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

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 …

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 …

The accuracy of the spectral difference method for measuring ultrasonic attenuation has
been investigated using tissue-mimicking phantoms. Attenuation coefficients of the phantom …

A practical and highly accurate method of estimation of the frequency-dependent slope of
the acoustic attenuation coefficient, α 1, using backscattered ultrasound energy is presented …

This paper studies imaging of tissue-specific ultrasound attenuation. A new method is
presented where the imaged parameter is the mean attenuation coefficient between the …

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 …

Ultrasonic attenuation is important not only as a parameter for characterizing tissue but also
for compensating other parameters that are used to classify tissues. Several techniques …
