given Riverside Research Institute medium as compared to the amount of power that would …

Apparatus is described for measurement of sound speed and ultrasound attenuation
coefficients by the substitution technique in the frequency range 3 to 8 MHz. Phase …

Ultrasonic attenuation coefficient measurements were made at 1.4, 4.2, 7.0 and 9.8 MHz
using a phase insensitive, radiation force balance technique. Ultrasonic attenuation …

This paper describes a novel technique for estimating ultrasonic attenuation coefficients.
The technique first employs a histogram analysis to estimate the number of tissues present …

Attenuation measurements were performed on the quadriceps femoris muscle of 10 normal
volunteers. The measurements were made using a statistical narrowband pulse echo …

Attenuation measurements of various tissue minicking phantoms and three different groups
of patients were obtained using a modified commercial sector scanner. Estimates of …

The measurement technique developed for in vivo assessment of ultrasound velocity in
mammalian tissue is described and discussed from the point of view of the limitations of the …

The parameter characterizing the acoustic attenuation in soft tissues is an indicator of tissue
state. A method which features autoregressive deconvolution and spectral smoothing is …

Ultrasonic spectrum analysis procedures have been developed to measure tissue
morphologic features that are not well depicted with conventional ultrasonography. This …
