Abstract
Energy-selective x-ray images are produced using two scintillating screens separated by an x-ray hardening filter. Photosensitive surfaces individually receive the light images from each screen. The resultant image transparencies are read out optically using a partially reflecting mirror between the transparencies and detecting the reflected and transmitted light. The x-ray spectral separation between the two acquired images can be further increased by using an x-ray source filter having a K-absorption edge in the vicinity of the region of overlap of the two spectra.
