ABSTRACT:
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.
