摘要

An apparatus for producing displays in the form of areas of well- defined illumination levels, in order to display a body subjected to penetrating radiation, and in particular X rays or gamma rays is provided. In this apparatus, the image is divided into two regions, the first corresponding to a narrow range of levels and the second, to a much larger range of levels. Means are provided in order to clearly differentiate the respective appearances of these two regions.
