The purpose of this communication is to report the results of acoustic-attenuation
measurements in mam-malian kidney tissue at frequencies up to 222 MHz and to comment …

In the estimation of ultrasound attenuation in biological tissue, diffraction phenomena
introduce bias due to their depth dependent filtering effect. The spectral high frequency …

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

Measurement of the slope of attenuation as a function of frequency to compute ultrasonic
attenuation coefficients for thin slices of tissue with ultrasonic pulse-echo techniques is …

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

Within the past few years significant advances have been made in the application of
ultrasound in medical practice, particularly in the diagnostic area. In fact, at the present time …

The spatial‐frequency spectra of the spatial properties of a scattering medium can be
determined from measurements of scattering over a number of angles or frequencies. In …

Phase cancellation effects can compromise the integrity of ultrasonic measurements
performed with phase sensitive receiving apertures. A lack of spatial coherence of the …

Optimized wideband attenuation estimations were performed on a tissue mimicking
phantom in a water tank with and without axial beam translation (ABT), and the results were …

The study described herein was undertaken to determine the role of proteins, in general,
and collagen, in particular, in the observed absorption and speed of ultrasound in biological …
