For many years, ultrasound has provided clinicians with an affordable and effective imaging
tool for applications ranging from cardiology to obstetrics. Development of microbubble …

Recently, dual-frequency transducers have enabled high-spatial-resolution and high-
contrast imaging of vasculature with minimal tissue artifacts by transmitting at a low …

A numerical scheme is developed to simulate the propagation of weak acoustic shock
waves in the atmosphere with no absorption. It generalizes the method previously …

In this paper, a recently developed wave-vector frequency-domain method for nonlinear
wave modeling is improved and verified by numerical simulations and underwater …

Focused ultrasound is an emerging therapeutic modality that has found clinical use for the
treatment of a number of serious medical conditions. It is an attractive treatment modality due …

Traditional ultrasound imaging takes into account linear propagation only. However, new
methods seek to exploit the nonlinear properties of tissues, which create a specific contrast …

Second-harmonic generation in non-linear media is investigated. A normal mode analysis is
proposed based on the Westervelt equation under the second-order approximation in …

Ultrasound plays a steadily increasing role in diagnostic and therapeutic medicine. The
ability to simulate medical ultrasound fields serves several purposes. First, the fabrication of …
