| Abstract: | Current trends in nuclear medicine to some degree, at least, reflect the level of sophistication available in the instrumentation. A technologically oriented speciality such as this might be expected to shift emphasis from time to time as stepwise advances are made in instrumentation. In its infancy, nuclear medicine concentrated on studies that could be accomplished with a single-probe system. The introduction of rectilinear scanners made imaging practical and of primary concern. Anger's gamma camera made combined static and dynamic studies possible using a single instrument--a decided advantage over previous methodology. The development of digital acquisition, processing, and display systems has had a profound effect on the recently increased emphasis on rapid dynamic studies. Computers are currently being applied to a broad range of clinical problems. Data preparation routines such as uniformity correction and data bounding often are used preliminary to more rigorous mathematical treatment. The development of reasonably low-cost, TV-type displays has greatly increased the quality of the computer display of the radionuclide imaging process. |
