Focused ultrasound offers a non-invasive way of depositing acoustic energy deep into the
body, which can be harnessed for a broad spectrum of therapeutic purposes, including …

Randomized phased arrays can offer electronic steering of a single focus and simultaneous
multiple foci concomitant with low levels of secondary maxima and are potentially useful as …

Abstract Flat, λ/2-spaced phased arrays for therapeutic ultrasound were examined in silico
and in vitro. All arrays were made by combining modules made of 64 square elements with …

Focused ultrasound (FUS) phased arrays show promise for non-invasive brain therapy.
However, the majority of them are limited to a single transmit/receive frequency and …

A 64-element, 1 MHz prototype dual-mode array (DMUA) with therapeutic and imaging
capabilities is described. Simulation and experimental results for the characterization of the …

Ultrasound phased arrays offer several advantages over single focused transducer
technology, enabling electronically programmable synthesis of focal size and shape, as well …

Dynamically focused and steered high frequency ultrasound imaging systems require arrays
with fine element spacing, wide bandwidths, and large apertures. However, these …

Spatial planar projection techniques propagate field measurements from a single plane in
front of a transmitter to arbitrary new planes closer to or further away from the source. A …

Ultrasound imaging is a widely used diagnostic tool but has limitations in the imaging of
deep lesions or obese patients where the large depth to aperture size ratio (f-number) …

A method for focusing high-intensity ultrasound (HIFU) through a rib cage that aims to
minimize heating of the ribs while maintaining high intensities at the focus (or foci) was …
