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.
