...current Congolese standards one of the bright spots in the nation's health picture is Beni -a village at the northeast tip of remote Kivu province. Beni's modern. Belgian-built hospital is staffed by two physicians on loan from the Irish Red Cross; a new X-ray machine and cases of operating-room equipment are stacked against its walls, and the dispensary is equipped with large stocks of antimalaria drugs. But the U.N.'s Irish doctors found the Belgians had made no attempt to control the spread of malaria by clearing swamps or spraying trouble spots...
Monitoring the operation through an image intensifier-a refined fluoroscope that produces an X-ray image 1,500 times Drighter than the old-style fluoroscopic screen-Drs. Sones and Shirey then release a tiny amount of radiopaque dye through the catheter into the aorta in order to locate the spot at which right and left coronary arteries join the circulation's main stem. "The rest," says Sones, 'requires only a little bit of simple dexterity." The catheter is successively slipped into both coronary arteries, and small injections of dye (2 cc. to 5 cc.) are sufficient to silhouette...
Half a Toothpick. With high-speed film, the resultant X-ray image is sharp enough to show blockages only one-fourth the width of a coronary artery, and to pick out collateral blood vessels only 80 microns in diameter-about half the thickness of a toothpick. Says Sones: "We hope eventually to be able to see vessels as small as 30 microns (.0012 in.) in diameter, because even vessels that small can act as effective collateral channels for blood from a diseased artery...
...another. Sacramento's Aerojet-General Corp., prime contractor for the Polaris missile's propellant, found that when the solid fuel was molded, bubbles tended to form, caused trouble in firing. To find the bubbles, the company had to haul the finished rocket motor to a giant X-ray laboratory, spend two to three weeks taking pictures. Aerojet's radiation experts went to work, found they could do the job in hours by slipping in a radioactive cobalt pill, using photon-counters to measure the rate of radiation. If it was steady, no bubbles. They kept improving their...
...modest house in a New England factory town, Alphege LeBlanc lies dying of cancer. He does not know it at first and hopes for the wonders of X-ray to take hold. LeBlanc is a simple man, a factory hand who never had the drive to get ahead and now dwells with thankfulness on the fact that at least his wife and children never went hungry. But as his illness continues to race through his body, he is more and more afraid that he was merely a provider, and not a very good one. A sense of failure edges...
