Briefly described, in an exemplary form, the present invention discloses a system, method and apparatus for X-ray Compton scatter imaging. In one exemplary embodiment, the present invention uses two detectors in a volumetric CT system. A first detector is positioned generally in-line with the angle of attack of the incoming energy, or, generally in-line of path x, where x is the path of the incoming energy. The first, or primary, detector detects various forms of radiation emanating from an object undergoing testing. In some embodiments, the present invention further comprises a Compton scattering system positioned generally normal to path x. In some embodiments, the Compton scattering subsystem comprises a second detector and a pin-hole collimator. The second detector detects Compton scattering energy from the object being tested.
