A new study provides the first visual evidence showing that brain circuits in living animals can be activated by ultrasound waves projected into specific patterns (holograms). Led by scientists at NYU ...

Thanks to Freescale Semiconductor Medical Applications guide, I give you this crash course in how ultrasound works. This non-invasive technique uses sound waves to create images of what’s inside of ...

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences in ...

Low-intensity pulsed ultrasound, with frequency tuned to match target cells, can break apart cancer cells without harming healthy blood cells. (Courtesy: iStock/Mohammed Haneefa Nizamudeen) Medical ...

Ultrasound waves, currently used in medicine for prenatal scans and other diagnostic purposes, could one day be used as a noninvasive way to control brain activity. Over the past two years, scientists ...

Ultrasound works by sending sound waves through the body. Doctors can recommend ultrasound therapy to treat pain. It may work best alongside other treatments. Many people know ultrasound as an imaging ...

Sonograms and ultrasounds are closely related but refer to different things. An ultrasound is an imaging tool that produces a sonogram. Often, the terms sonogram and ultrasound are used ...

Radio-frequency (RF) control of an ultrasonic phononic crystal was achieved by encapsulating it in a composite of high k-10% KF-doped BaTiO 3 dielectric nanoparticles with poly(N-isopropylacrylamide) ...
