...with a hollow core. It is a cousin of the CAT scanner that nearly a decade ago wedded the technique of X rays with computer technology to give cross-sectional views of internal body structures, not just bones but soft tissues as well. But scanning by CAT (for computerized axial tomography) is limited to anatomy. It lets doctors see an organ's shape and form, but cannot tell how it is functioning. PET (for positron emission tomography) allows the physician to examine the brain and body in ways never before possible, providing metabolic portraits, and revealing the rate...
...Tufts University, and Research Engineer Godfrey Hounsfield, 60, of the British firm EMI Ltd., brooded over the same mathematical puzzle and independently reached the same solution. The puzzle: how to produce an X-ray image of tissue at any depth within a patient. The result: the CAT (for computerized axial tomography) scanner, a medical marvel now used in hospitals round the world. Last week the two scientists learned that they have something else in common: they will share the 1979 Nobel Prize in Physiology or Medicine and its accompanying cash award...
...machine, known as the computed axial tomography scanner (CAT), allows doctors to take three-dimensional x-rays of a patient through the use of a rotating x-ray tube...
...cleaners, clerks) so sharply that, for example, wages and benefits now take 70% of the budget of New York Hospital-Cornell Medical Center, vs. 35% only 20 years ago. The introduction of expensive machinery raises rather than lowers labor costs. For example, if a hospital buys a CAT (computerized axial tomography) scanner, a kind of super X-ray machine, it must also hire highly trained, highly paid technicians...
Seventy-six years later, the computerized axial tomography, or CAT, scanner, hailed as the greatest advance in radiology since the discovery of X rays, appeared on the medical scene. Combining X-ray equipment with a computer and a television cathode-ray tube, this revolutionary diagnostic device can visualize cross sections of the human body to detect, among other disorders, tumors, blood vessel damage and bile duct obstructions. But whereas an X-ray machine cost $50 in 1896, today's CAT scanner may run to $700,000 or more...
