Echolocation is a powerful technique that uses sound or ultrasound waves to locate objects and surfaces. Ships and submarines, for example, use it to avoid collisions, and dolphins and microbats use it to locate prey (see image). Hongbin Yu and co-workers from the A*STAR Institute of Microelectronics, Singapore, have now used echolocation to measure the inclination of millimeter-sized ultrasonic sensors. In this new setting, their technique should extend the capabilities of devices that already use ultrasonic components, whether for locating defects in materials, visualizing anatomical structures or determining range. http://phys.org/news287215740.html Physics Wed, 08 May 2013 07:09:06 EST news287215740 Ultrasound technology could soon experience a significant upgrade that would enable it to produce high-quality, high-resolution images, thanks to the development of a new key material by a team of researchers that includes a professor in the Department of Biomedical Engineering at Texas A&M University. http://phys.org/news281704974.html Chemistry Tue, 05 Mar 2013 11:23:04 EST news281704974 Electrical engineers at Oregon State University have discovered a way to use high- frequency sound waves to enhance the magnetic storage of data, offering a new approach to improve the data storage capabilities of a multitude of electronic devices around the world. http://phys.org/news280073024.html Physics Thu, 14 Feb 2013 14:04:15 EST news280073024 In one University of Illinois lab, invisibility is a matter of now you hear it, now you don't. http://phys.org/news213461504.html Physics Wed, 05 Jan 2011 14:52:14 EST news213461504 Columbia University bioengineer Elisa Konofagou is making waves when it comes to researching treatments for degenerative brain disorders such as Alzheimer's and Parkinson's. These aren't just any waves; they're ultrasound waves. http://phys.org/news198246365.html Medicine & Health Tue, 13 Jul 2010 13:40:01 EST news198246365 High resolution ultrasound should be the imaging test of choice when evaluating patients with foot drop (an inability or difficulty in moving the ankle and toes causing uncontrolled slapping of the foot while taking a step), according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA. Ultrasound imaging is non-invasive and involves exposing part of the body to high-frequency ultrasound waves to produce pictures of inside the body. http://phys.org/news192357169.html Medicine & Health Thu, 06 May 2010 10:30:01 EST news192357169 There's a new interventional radiology tool showing promise in the treatment of uterine fibroids: magnetic resonance-guided focused ultrasound (MRgFUS), a minimally invasive treatment that uses high-energy ultrasound waves to generate heat at a specific point to destroy uterine fibroid tissue and relieve symptoms. A study of more than 100 patients shows that women can get lasting relief from uterine fibroid-related symptoms with MRgFUS—thus avoiding myomectomy, the surgical removal of uterine fibroids, or hysterectomy, major abdominal surgery to remove the uterus, say researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla. http://phys.org/news187870496.html Medicine & Health Mon, 15 Mar 2010 12:10:02 EST news187870496 It looks more like an iPod than a medical tool. But the latest miniature ultrasound device created by Cornell biomedical engineering graduate student George K. Lewis could one day introduce a whole new level of home therapy for arthritis, injury and other painful ailments. http://phys.org/news185712339.html Medicine & Health Thu, 18 Feb 2010 11:00:02 EST news185712339 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 testing of buildings and bridges, and novel underwater stealth technology. http://phys.org/news165064464.html Physics Wed, 24 Jun 2009 12:15:56 EST news165064464
