In a new study in rats, Stanford Medicine scientists used ultrasound-activated nanoparticles to deliver ketamine and ...

It enables display of more details of bright areas and dark areas. SCI (Spatial Compounding Image™) controls the ultrasound beam electronically by steering, and compounds many scan lines.

US researchers are building a non-invasive system using ultrasound to deliver drugs anywhere in the body with precision, as ...

An illustration showing the breaks in the blood-brain barrier caused by focused ultrasound. There a couple of ways the team could be sure that their 256-channel ultrasound system was actually working.

In a study published in the journal Nature Nanotechnology, the team showed in rats that their system can deliver ketamine to specific regions of the brain ...

In a groundbreaking development, researchers at Stanford University are designing a non-invasive drug delivery system that uses ultrasound and sugar-stabilised nanoparticles to target specific areas ...

The other feat is transforming the ultrasound beams into something we can hear. This is accomplished by projecting each beam at slightly different frequencies — one at 40,000 Hz and one at ...

Ultrasound, at a frequency of 980,000 cycles per second, shot through intervening brain tissues but not in sufficient intensity to damage them.

The beam of ultrasound can be steered across three dimensions, to focus on a desired area within the body that is only a few millimeters across. The ultrasound is thought to cause the perfluorocarbons ...

Magnetic resonance (MR) imaging-guided ultrasound, a technology that involves highly-targeted ultrasound beams and monitoring their effects through imaging, has shown to help treat symptoms of ...
