Abstract
A conventional flat bed greyscale digitizing scanner which operates in conjunction with reflective media is retrofitted with an adapter assembly which permits it additionally to process X-ray film transparencies. Accordingly, the resulting apparatus, in addition to performing digitization of data imprinted on reflective media, is also capable of digitizing X-ray images on X-ray film transparencies. The adapter assembly is constucted to be easily mounted on a conventional flat bed scanner to permit the scanner to process the film transparencies, and to be easily removable from the conventional scanner to permit the scanner to operate in a conventional mode to process reflective media. The scanner may be constructed to perform transparency digitization and to provide an optical density dynamic range greater than the prior art CCD technology used in the more expensive machines will allow.
