Abstract
The present invention concerns an X-ray examination apparatus allowing to produce images of an object through the scanning of the object by at least two fan-shaped beams having different energy spectra, and obtained from a single X-ray source, thereby allowing to obtain simultaneously images of the object adapted to contain different informations.

An X-ray examination apparatus comprising an X-ray tube producing X-rays, collimation means defining a first and a second separated fan-shaped flat beams of said X-rays, means for scanning an object by said first and second fan-shaped beams along a mean direction substantially perpendicular to the planes of said first and second fan-shaped flat beams, receiving means sensitive to the X-rays, means for conferring to each said first and second beams a different energy radiation spectra prior to their crossing through the object to be examined, and wherein the receiving means comprise a first and a second receiving assemblies each forming a shadow image of the object respectively from the first and the second fan-shaped flat beam in order to simultaneously obtain at least two images of the object.
