Patent ID: 7742564

Claim:
A method for detecting an image of an object, the method comprising: (a) generating a first divergent X-ray beam from a non-synchrotron X-ray source, the first X-ray beam having a polychromatic energy distribution and characteristic lines Kα1 and Kα2 with X-ray energies above 40 keV; (b) positioning a single monochromator crystal in a predetermined position to directly intercept the first X-ray beam and select and produce a second divergent X-ray beam having a predetermined energy level, the second x-ray beam containing a narrow energy band including characteristic lines Kα1 and Kα2 with X-ray energies above 40 keV; (c) positioning an object in a path of the second X-ray beam for transmission of the second X-ray beam through the object and emitting from the object a transmitted X-ray beam; (d) directing the transmitted X-ray beam at an angle of incidence upon an analyzer crystal; and (e) detecting an image of the object from a beam diffracted from the analyzer crystal.
