Abstract
A radiation imaging system and method is disclosed for producing an enhanced television image of diagnostic quality from a light image produced by a common image tube and corresponding to a pattern of penetrative radiation from a subject. A source directs radiation such as X-rays through the subject and the image tube converts the emergent radiation pattern to a corresponding visible light image at an output phosphor. A television apparatus including an image isocon pickup tube views the output light image at a tube input face by way of a lens assembly and converts the light image to electrical, including video signals. A television monitor reconverts the electrical signals to a visible television image of enhanced quality representing the pattern of radiation from the subject. The television monitor includes an improved cathode ray tube with a planar output face, a small focal spot, and improved phosphor.
