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 ...

One way sound: A new material will allow for improved ultrasound imaging
Most roads allow cars to flow in both directions. However, in some circumstances, such as congested city streets, it makes sense to limit traffic to one direction only. With electricity it is also useful to "rectify"currents ...
