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, ...

Researchers produce first laser ultrasound images of humans

For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient's skin, sound waves generated by the probe travel through the skin, bouncing off muscle, fat, ...

'Seeing' single cells with sound

If you are a researcher who wants to see how just a few cells in an organism are behaving, it is no simple task. The human body contains approximately 37 trillion cells; the fruit fly flitting around the overripe bananas ...

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 ...

Using sound waves to make patterns that never repeat

Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials ...

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.
