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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
