Sound waves detect disease related changes in red blood cell shape
http://www.cell.com/biophysj/abstract/S0006-3495(13)00624-3 Ryerson University investigators used photoacoustics to create detailed images to detect changing shapes of red blood cells associated with diseases including maria, sickle cell anemia and certain types of cancer. A drop of blood is placed under a microscope that picks up sounds produced by the cells. Researchers then focus a laser beam on the samples.…

Medical device data shared via ultrasound, real-time treatment enabled
http://www.buffalo.edu/news/releases/2013/05/0570.html Navy sonar technology is being miniaturized by University at Buffalo professor Tommaso Melodia to be applied inside the human body to treat diseases like diabetes and heart failure in real time. A network of wireless body sensors that use ultrasounds could be used to wirelessly share information between medical devices implanted in or worn by diabetic/heart failure patients. Previously, researchers focused…

Bats use of sonar applied in medical ultrasound machines
http://news.discovery.com/tech/innovations-inspired-by-animals-130325.htm Bat sonar has long had an edge over man-made sonar and ultrasound devices, but scientists are working to decrease that gap. Nathan Intrator of Tel Aviv University’s Blavatnik School of Computer Science, in collaboration with Brown University’s Jim Simmons, created mathematical models that improve our understanding of the ultrasound process. “Animals explore pings with…
