Ultrasonic pulse echo imaging in inhomogeneous media suffers from significant lateral and
contrast resolution losses due to the defocusing effects of the inhomogeneities. The losses …

The present paper is intended as a review (over 300 Refs.) of some basic concepts and
modern investigations of nonlinear and thermoviscous phenomena in acoustic fields in …

Optimal selection of parameters is presented for the angular spectrum approach (ASA) to the
numerical calculation of acoustic fields radiated by planar transducers and linear arrays with …

An existing model, the Bergen code, is used to simulate the propagation of ultrasonic beams
of finite amplitude, due to rectangular and square sources. It is found that the edges of the …

Harmonic imaging can improve contrast between contrast agents and tissue when imaging
microvasculature. However, the factor limiting contrast enhancement is harmonic signals …
