Designing ultrasound tools with Lego-like proteins

Ultrasound imaging is used around the world to help visualize developing babies and diagnose disease. Sound waves bounce off the tissues, revealing their different densities and shapes. The next step in ultrasound technology ...

Designing an acoustic diode

Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned by researchers ...

Ultrasound scalpel destroys liver tumors

Focused ultrasound can effectively destroy tumor cells. Until now, this method has only been used for organs such as the prostate and uterus. At the European Congress of Radiology, Fraunhofer researchers will present a method, ...

Ultrasound, nanoparticles may help diabetics avoid the needle

A new nanotechnology-based technique for regulating blood sugar in diabetics may give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections – rather ...

First acoustic metamaterial 'superlens' created

A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural ...

New imaging technique peers inside living cells

To undergo high-resolution imaging, cells often must be sliced and diced, dehydrated, painted with toxic stains, or embedded in resin. For cells, the result is certain death.

Research brings 'smart hands' closer to reality

Using your skin as a touchscreen has been brought a step closer after UK scientists successfully created tactile sensations on the palm using ultrasound sent through the hand.

New "tricorder" technology might be able to "hear" tumors growing

When Dr. Leonard "Bones" McCoy needs to diagnose an ill member of the Starship Enterprise, he simply points his tricorder device at their body and it identifies their malady without probing or prodding. Similarly, when Capt. ...
