ABSTRACT:
In accordance with the invention, an apparatus for diagnostic radiographic imaging comprises an x-ray source for providing an exposing dose of x-rays and a first radiation receptor for detecting imagewise modulated x-rays are emitted from the x-ray source and from an imaging object interposed between the source and the first receptor; the first receptor thereby provides a first image of the object. A second radiation receptor for detecting imagewise modulated x-rays that are emitted from the first receptor is situated behind the first receptor and comprises x-ray converter means and detector means for detecting a converted x-ray image; the second receptor provides a digital second image of the object. Also in accordance with the invention, a method for forming two diagnostic radiographic images from a dose of x-rays comprises exposing an imaging object interposed between an x-ray source and a first radiation receptor and detecting by the first receptor imagewise modulated x-rays emitted from the x-ray source and the object; a first image of the object is thereby provided. Imagewise modulated x-rays emitted from the first receptor are detected by a second imaging receptor that is situated behind the first receptor and comprises x-ray converter means and detector means for detecting a converted x-ray image; a digital second image of the object is thereby provided.
