Systems and methods for detecting an image of an object by use of X-ray beams generated by multiple small area sources are disclosed. A plurality of monochromator crystals may be positioned to intercept the plurality of first X-ray beams such that a plurality of second X-ray beams each having predetermined energy levels is produced. Further, an object to be imaged may be positioned in paths of the second x-ray beams for transmission of the second X-ray beams through the object and emitting from the object a plurality of transmission X-ray beams. The X-ray beams may be directed at angles of incidence upon a plurality of analyzer crystals for detecting an image of the object.
