Two single element, 8 mm focal depth, 6 MHz PZT-5A 40% volume fraction 1-3 composite
Fresnel aluminum lens based therapeutic ultrasound transducers for use in small animal …

High element density and strict constraints of the element's size have significantly limited the
design and fabrication of 2-D ultrasonic arrays, especially fully sampled 2-D arrays …

Fabricating PMN–PT composites, the core component of high-frequency (> 30 MHz)
transducers, remains challenging due to their poor machinability and ultrasmall kerfs. This …

Compact high-frequency arrays are of interest for clinical and preclinical applications in
which a small-footprint or endoscopic device is needed to reach the target anatomy …

Approximately 4 million people with peripheral artery disease (PAD) present with critical
limb ischemia each year, requiring urgent revascularization to avoid loss of limb. Minimally …

This article presents the first fully integrated 2-D array of electronic-photonic ultrasound
sensors targeting low-power miniaturized ultrasound probes for endoscopic applications …

Here we introduce electrostrictive hot-pressed lead magnesium niobate (PMN) with low lead
titanate (PT) doping as a candidate transparent transducer material. We fabricate …

Two-dimensional sparse arrays and row-column arrays are both alternatives to 2-D fully
addressed arrays with lower channel counts. Row-column arrays have recently …

The challenge of achieving micro kerf () for high-frequency (MHz) composites presents a
substantial barrier to the progress of PMN–PT (–) transducers. The ultrafast laser offers a …
