New ultrasound-based wearable measures blood pressure from deep vessels without a cuff, improving accuracy and comfort.

Conventional ultrasound (cUS) and functional ultrasound (fUS) both utilize megahertz-level sound waves to image inside the body; however, beyond this, the similarities end. This article aims to ...

Biomedical engineers at Johns Hopkins report they have worked out a noninvasive way to release and deliver concentrated amounts of a drug to the brain of rats in a temporary, localized manner using ...

Supertex has introduced the HV738 and the HV748, two new, fully integrated, high voltage, high speed, four channel ultrasound pulser ICs. These ICs combine logic control circuitry, level translators, ...

Using ultrasound to boost the effectiveness of IV thrombolysis—an approach called sonothrombolysis—is feasible but does not improve functional outcomes in patients with acute ischemic stroke, results ...

STMicroelectronics has introduced an integrated low-noise ultrasound pulse controller that provides four independent channels, each of which generates precisely controlled high-voltage pulses to drive ...

Through a clever combination of two imaging modalities, scientists from Caltech and USC have developed a new technique that can quickly provide 3D ...

Encapsulated microbubbles (EMBs), tiny gas-filled bubbles coated in lipid or protein shells, play a central role in biomedical ultrasound. When exposed to ultrasound waves, EMBs contract, resulting in ...
