The principles of a narrowband technique for pulse echo attenuation measurements are
presented. Experiments are described which compare the attenuation in tissue-mimicking …

Among emerging medical diagnostic imaging modalities, positron emission tomography,
often abbreviated to its acronym" PET", belongs in the category of nuclear medicine. Indeed …

Purpose: This study validates that phase aberrations in breast magnetic resonance-guided
focussed ultrasound (MRgFUS) therapies can be corrected in a clinically relevant time frame …

The capability of ultrasound transmission tomography to reconstruct acoustic parameters of
proven histological relevance like acoustic speed and attenuation has been established …

The quantitative capability of pulsed Doppler ultrasound in clinical practice is limited by the
effects of frequency-dependent attenuation of ultrasound in tissue, as well as several other …

Ultrasonic waves of at least three independent frequency bands having different center
frequencies are transmitted into a living body from its skin surface and reflected waves are …

A known method for the determination of the attenuation coefficient of tissues involves the
measurement of the center frequency downshift of Gaussian spectra. The tissue is generally …

The ultrasound phantoms used to educate medical students should not only closely mimic
the ultrasound characteristics of human soft tissues but also be inexpensive and easy to …

This paper deals with computed imaging techniques for ultrasonic transmission tomography.
Cross-sectional images of the refractive index in soft biological tissues can be obtained by …

For medical workers, ultrasound phantoms for human soft tissue are used not only for
accuracy management of ultrasound diagnosis but also to aid ultrasound‐guided needle …
