Abstract

Photofluorographic cameras or the Odelca type have been widely used ror more than 25 years in mass chest x-ray examination. Such cameras provide full diagnostic detail on a reduced size low cost photograph, but although they are equipped with extremely wide aperture optics, the required x-ray dose is somewhat higher than that for a full size radiograph. This disadvantage, which has limited the range of application of photofluorography in the past, is eliminated in the new Oldelft "Electrodelca". This camera includes an electro-optical image intensifier of the proximity focussed type, the output of which is fiberoptically coupled to the photographic film. The design criteria for this approach are discussed and performance data are presented.
