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

Intersecting two slightly different frequency beams of ultrasound, e.g., 40 kHz and 39.5 kHz, researchers produce a new difference frequency wave of 500 Hz, which human beings are able to hear.

"When two ultrasonic beams of slightly different frequencies, such as 40 kHz and 39.5 kHz, overlap, they create a new sound wave at the difference between their frequencies – in this case, 0.5 ...

The ultrasound beam travels through the administered gel and subsequently penetrates skin, subcutaneous tissue, the chest-wall muscles, the ribs, the intercostal muscles, ...

The Insightec Exablate Neuro, a focused ultrasound platform, instructs how many beams should be used to do the treatment, then neurosurgeons might do what Dr. Jeff Elias calls “test shots, just ...

There were clinical benefits to putting patients under a steady ultrasound beam during carotid endarterectomy, the phase III sham-controlled SONOBIRDIE trial found.

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. advertisement.

Conventional drug delivery is inefficient and imprecise. Through a series of preclinical experiments, researchers from the University of Utah have optimized a novel, targeted method of delivery ...

An ultrasound beam is directed at the suspected tumor. Once the micro bubbles reach the area of the brain, the ultrasound gets them oscillating and the blood-brain barrier starts to open.
