ABSTRACT:
An X-ray system includes an X-ray receptor producing on its area a light image with a finite range of intensities. Two or more video tubes scan the same area of the image to generate corresponding electrical output signals, each tube having a bias electrode controlled by a variable voltage source so that one tube generates output signals whose amplitude corresponds to one portion of the range of light intensities at the image area and the output signals of the other tube correspond to a different range portion of the image area light intensities.
