The term “tissue characterization” covers a range of meanings from qualitative assesments
to scientific measurements. From the vast literature available the selection presented is used …

Several acoustic transmission and reflection technique measurements were carried out to
determine mechanical properties (acoustic attenuation and velocity) versus frequency of …

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 …

An alternative to rectification is proposed for detection of an ultrasonic signal for medical or
non-destructive evaluation applications. With this technique the envelope of the ultrasonic …

Time-delay spectrometry (TDS) can conveniently be used for calibration and performance
evaluation of piezoelectric electroacoustic transducers. The main emphasis of the work …

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 …

This chapter presents a number of calibration techniques for hydrophones used in ultrasonic
exposimetry. The topic of hydrophone calibration methods is central to ultrasonic …

The use of the technique of time-delay spectrometry in ultrasonic transducer characterisation
is described for both transmitters and receivers. The principles of the technique, the choice …

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 …

A reflection mode proof-of-concept medical ultrasound imager based on time delay
spectrometry has been developed and tested. The system uses a broad band swept …
