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.

A non-rotational CT or multiple dimensional measurement or tomography or 3D imaging system which images a subject comprising two or more substances, the system comprising:
- an x-ray source configured to illuminate the subject, with x-rays having at least two different energy levels;
- an x-ray measuring device having at least one two dimensional detector and configured such that the subject can be located between the x-ray source and the x-ray measuring device, the x-ray measuring device further configured to detect the x-rays after the x-rays have passed through the subject;
- wherein the x-ray measuring device is further configured to perform a premeasurement calibration, the calibration being performed using each material component and composites of each material component of various thicknesses,
- wherein the x-ray measuring device is further configured to identify at least one substance in at least one pixel of the image.
A method of 3D imaging a subject, the method comprising:
- providing an x-ray source and an x-ray measuring device having at least one two dimensional detector and configured to have the subject between the x-ray source and the x-ray measuring device;
- illuminating the subject, with x ray beam from the x-ray source from plurality of positions through movement or VOI or at least one component moves, with x-rays having at least two or three different energy levels;
- detecting, by the x-ray measuring device, the x-rays after the x-rays have passed through the subject;
- performing a pre-measurement calibration using each material component and composites of each material component of various thicknesses;
- and
- producing at least one image.
