Laboratory 3D X-ray computed tomography (XCT) is the most promising method for nondestructive and fully three dimensional characterizations of nanostructures. However due to conceptual limitations, commercial laboratory XCT devices are still an order of magnitude or more above the desired specifications in order to characterize 100 nm or smaller structures within a sufficient field of view.

Currently industrial X-ray computed tomography (XCT) is just touching the nanometer scale and is still suffering several severe limitations. The main limitations of XCT currently avoiding the application on chemical and structural nano-scale characterization are found in the limited field of view, X-ray source, detector, XCT system itself and in the lack of a method for comprehensive chemical and structural analysis.
