Strip away the interference that ultrasound scanners ordinarily pick up from muscle and skin and you have a better chance of saving not only images of the body's inner workings, but also a great deal of space, time, and money. Engineers at the University of Rochester (Rochester, NY) have devised a way to store such slimmed-down ultrasound scans. The patented technique junks the unneeded echoes from soft tissue and saves data only from the underlying organ, all the while whittling the size of a digitized ultrasound file image to one-twentieth of what's now required. "While existing JPEG and MPEG technologies work from the assumption that an image has a photographic origin, our technology recreates an image based on the assumption that it's working with data gathered through a pulse-echo system," explains Kevin Parker, professor of electrical engineering at Rochester. "It's a method of reconstructing images that's in step with the way ultrasound scanners collect data," and about 20 times faster. Phone (716) 275-4151.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
