An imaging system includes an x-ray source configured to emit a beam of x-rays toward an object to be imaged, a detector configured to receive x-rays that are attenuated by the object, a data acquisition system (DAS) operably coupled to the detector, and a computer operably coupled to the DAS. The computer is programmed to obtain scan data with two or more incident energy spectra, identify one or more material triplet combinations based on data obtained prior to obtaining the scan data, decompose the obtained scan data into three or more basis materials based on the identified one or more material triplet combinations, and generate an image using the decomposed scan data.
