Ultrasonic attenuation and backscattering were measured for bovine brain, spleen and liver
and for porcine iiver as a function of time after excision for times up to 120 hr. The …

Measurements are reported on the ultrasonic attenuation coefficient, the velocity of sound
propagation and the differential scattering coefficient (for 180° scattering) for 3 types of …

A modified version of pulse echo technique was used to measure the attenuation a and
backscattering α bs coefficient of ultrasound (frequency range 1-10 MHz) in freshly excised …

Ultrasonic attenuation and backscattering coefficients and speed of sound were determined
experimentally, as functions of frequency, in samples of fresh mammalian brain, liver and …

This is the second in a series of two papers reporting results collected on ultrasonic
propagation properties, namely, velocity, attenuation, and backscatter of various mammalian …

Ultrasonic attenuation over the frequency range of 1.5–10 MHz has been measured as a
function of temperature for porcine liver, backfat, kidney and spleen as well as for a single …

Ultrasonic B‐mode images are formed from echoes backscattered from tissue structures in
the body. Quantitative analysis of this signal from tissues may provide additional information …

Quantitative backscattering measurements have been made using the substitution method
used to measure the scattering properties of blood previously. We have obtained preliminary …
