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.
Fifty-six-year-old Pasquale Russo has been doing metalwork for more than 30 years in a tiny southern Italy village. Many craftsmen like him brought with them fabrication skills when they came from the Old World to America.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
