A new computed tomography (CT) scanner from Imatron Inc. could eliminate 20 to 40 % of the 2 million angiograms performed annually in the U.S. It uses electron beam technology (EBT) that is based on a scanning electron beam that scans at speeds of once every 50 to 100 milliseconds. Unlike angiograms, EBT is non-invasive. It allows doctors to see coronary arteries without the unpleasant procedure of inserting a tube into the patient's artery. "The EBT scanner provides a very focused image," says Ray Rand, an Imatron physicist. Other possible applications for EBT include scanning luggage for bomb detection at airports.

These free camps are designed for children ages 10 to 18. Attendees are introduced to 3D CAD software and shown how 3D printers can make their work a reality. Many classes were nearly 50 percent girls and 50 percent boys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
