Ultrasound fields in an attenuating medium
Ultrasound fields propagating in tissue will undergo changes in shape not only due to diffraction, but also due to the frequency dependent attenuation. Linear fields can be fairly well predicted forExpand

A convolve–multiply–convolve SAW processor for a transmultiplexer
A study of an analogue transmultiplexer element of an on-board multicarrier demodulator (MCD) using a surface acoustic wave (SAW) processor is made in this paper. The theoretical analysis andExpand
Nonlinear acoustic wave propagation in tissue medium
Measurements to comply with labeling standards and FDA requirements for diagnostic equipment are performed in water, a medium readily available and easy to use. To predict the fields in tissue, anExpand
Diffraction phenomena with co-axial plane piston transducers
Using an exact theory of Beissner an experimental methodology is developed to accurately measure the effective radii of unfocused, circular plane piston transducers. The transient and steady-stateExpand
