Abstract
An apparatus which allows monochromatic radiographs to be produced using conventional "table top" Coolidge tube generated x-rays, comprises of the use of known bent crystal x-ray diffractive optics to produce radiographic images. The apparatus for producing the desirable x-ray radiation in a predetermined maximum intensity includes a crystal of the type mentioned above which focuses the x-rays emitted from the tube, the crystal and tube being mounted on a linear translation table. In addition, a method of mammography and differential angiography employing that device are presented. Resolution of mammographs are improved and the method which uses images obtained with radiation above and below the absorption edge of the dye being used to detect anomalies in a circulatory system allows the use of dramatically reduced dye concentrations.
