1. A method for inspecting a component comprising a plurality of constituents, said method comprising: alternately irradiating the component with radiation characterized by at least two energy spectra to scan the component, wherein a first one of the energy spectra is different than a second one of the energy spectra; receiving data corresponding to each of the energy spectra; processing the data to generate a multi-energy data set; and decomposing the multi-energy data set to generate a plurality of material characterization images in substantially real-time.
