X-ray apparatus has a scintillation screen showing a light image in an area viewed by two or more video camera tubes. The tubes receive a projection of the light image in two different ranges of light intensities and generate electrical signals corresponding to the light intensities. The signals are combined to reconstruct the image. Alternatively two or more camera tubes view different portions of the image area generating multiple signal outputs which are reconstructed in a single, continuous display.

For converting to electrical signals an image area having a range of light intensity values at the area, apparatus comprising: an X-ray source; a scintillation screen having an image area responsive to X-rays from the source to produce a secondary, light image at the area; two or more electro-optical means viewing the image area and including optical means distributing light from the image area including optical means simultaneously separating the secondary image into at least two images with different intensity patterns and directing the different images simultaneously on separate paths, and at least two photoelectrically responsive means, one in each path, and each generating electrical area signals respectively corresponding to light intensities from the area viewed.
