Nucleoplasty (literally, removing the nucleus) is aimed at relieving that pressure. Using only local anesthesia and light sedation, which allows the patient to remain awake, the doctor inserts a needle into the distended disk and is guided by an X-ray imaging system that reveals the needle's position at all times. A wandlike device is then threaded through the needle and into the disk. There it emits a burst of radio-frequency energy that heats and almost instantly vaporizes the excess tissue, providing in turn almost instant pain relief...
...X-RAY VISION Today's preferred technology for looking through things is the same one Wilhelm Roentgen used to photograph the bones in his wife's hand in 1895, although the newest X-ray devices are considerably more powerful. Last September, for example, the U.S. Customs Service placed an order worth more than $25 million for 15 truck-based X-ray inspection systems made by American Science and Engineering, Inc., in Billerica, Mass. Using a technique in which images are made from X rays scattered back from objects (rather than passing through them), AS&E's systems can spot--with...
...over for inspection. Castano says he trusts his 12 employees to stay away from the drug smugglers, but he pays his men only $50 a week, and that makes them easy marks for even small bribes. Customs officers take no chances. They direct Castano's Chevy to a large X-ray machine, big enough to scan two semis at once, that can sometimes detect what the sniffer dogs may miss...
...must have been walking down the street and spotted the open wine bar. She could not resist the urge to drink and her visceral impulse seized the opportunity. These thoughts swirled around my head as I haphazardly read about the x-ray process that the late artist had used to make his floral prints. The image of her floral dress lingers in my memory. Her action clashed with the aura of the dress and with the aura of the room...
Digital mammography improves these odds by giving radiologists electronic eyes. The picture is taken the same way--by sending X rays through breast tissue compressed between two small plastic plates. But instead of transferring the X-ray image to film, digital mammograms translate the picture into bits of information that are stored on a computer. The radiologist can then manipulate the image by zooming in on problem areas or adjusting the contrast in bleak, featureless regions to single out suspicious growths...
