Abstract: An x-ray tomography system which can generate a qualitative 3D image of a region of interest using a an x-ray source, the x-ray source configured to emit x-ray radiation at the region of interest. The x-ray radiation or the x-ray source or the relative position of the x ray source configured to be moved in a two dimensional plane. An x-ray detector including a plurality of detector elements arranged in a two dimensional plane opposite the x-ray source, the x-ray detector configured to detect x-ray radiation after attenuation by the subject and provide an indication of the detected x-rays. And a processor configured to receive the indication of the detected x-rays and resolve the detected x-ray radiation into a three dimensional image. The three dimensional image is qualitative in nature.

Abstract: Methods for quantitatively separating x-ray images of a subject having three or more component materials into component images using spectral imaging or multiple-energy imaging with 2D radiographic hardware implemented with scatter removal methods. The multiple-energy system may be extended by implementing DRC multiple energy decomposition and K-edge subtraction imaging methods.
