title: Imaging gas detectors for medicine and biology.
abstract: A brief overview is given of the operating characteristics of gas filled detectors especially multi-wire proportional chambers and gas scintillators as applied to imaging of ionizing radiation for medicine and biology. Both intrinsic and practical limitations on these devices and their implications on their areas of applicability are discussed. Comparisons are made with other imaging technologies.
