In recent years Ultrasonic imaging systems have provided valuable diagnostic information in
the clinical enviroment with no apparent harm to the patient. Much effort has gone into …

When ultrasonic fields interact with tissue, the characteristics of the field will be affected in a
manner which is dependent upon the acoustic properties of the tissue. An expanding set of …

This study was undertaken to evaluate the potential of computed ultrasonic tomography for
providing local, quantitative values of an ultrasonic index of attenuation, on the premise that …

Ernest J. Feleppa and Mykola M. Yaremko transmitting to the receiving transducer through a
given Riverside Research Institute medium as compared to the amount of power that would …

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

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

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 …

In a study involving 10 different sites, independent results of measurements of ultrasonic
properties on equivalent tissue‐mimicking samples are reported and compared. The …

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 …

In the measurement of acoustic attenuation that obeys a power-law α= β f, the traditional
through-transmission method uses only the amplitude information of the recorded pulses to …
