Ultrasonic beams fired through a 3D-printed metasurface can create localized pockets of sound that are inaudible to ...

To release the drug, the researchers played back an ultrasound—a sound wave with a frequency beyond the upper limit of human hearing—of 300 or 900 kilohertz. The beam of ultrasound can be ...

Audible enclaves are created at the intersection of two ultrasound beams. The researchers used two ultrasound beams at slightly different frequencies to do this. When the beams intersect ...

As a result, we developed a technology that can freely, quickly and accurately generate and change the form of ultrasound beams," and added, "We hope that the results of this research are used in ...

That makes containing them difficult. To sidestep that issue, the researchers use two beams of ultrasound waves — the type used in medical imaging — which vibrate at a frequency way above ...

Ultrasonography can be used to examine the tissue layers of the chest wall. The ultrasound beam travels through the administered gel and subsequently penetrates skin, subcutaneous tissue ...

To release the drug, the researchers played back an ultrasound – a sound wave with a frequency beyond the upper limit of human hearing – of 300 or 900 kilohertz. The beam of ultrasound can be steered ...

Kassell describes the way it works as “analogous to using a magnifying glass to focus beams of light on a point and burn a hole in a leaf.” “With focused ultrasound, instead of using an ...

Sonolysis, an application of therapeutic ultrasound, reduced periprocedural cerebrovascular events during carotid endarterectomy. The safety profile of sonolysis was supported by a reported lack ...

A focused ultrasound beam can be precisely focused on target tissue deep within the body to create heat to kill tissue, and the tissue in between is spared. For years, there were no good options ...

To release the drug, the researchers played back an ultrasound – a sound wave with a frequency beyond the upper limit of human hearing – of 300 or 900 kilohertz. The beam of ultrasound can be ...
