    摘要： A diagnostic imaging system includes a high frequency electromagnetic energy source that emits a beam of high frequency electromagnetic energy toward an object to be imaged. An energy discriminating (ED) detector receives high frequency electromagnetic energy emitted by the high frequency electromagnetic energy source. The ED detector includes a first direct conversion layer and a second direct conversion layer. The first direct conversion layer comprises a first direct conversion material and the second direct conversion layer comprises a second direct conversion material that is different from the first direct conversion material. A data acquisition system (DAS) is operably connected to the ED detector and a computer operably connected to the DAS.

    摘要： A CT system in an example comprises one or more high frequency electromagnetic energy sources, a detection assembly, a data acquisition system (DAS), and a computer. The one or more high frequency electromagnetic energy sources emit one or more beams of high frequency electromagnetic energy toward an object to be imaged. The detection assembly is capable of measuring a plurality of projection data at a same projection path that corresponds to a plurality of distinct incident energy spectra. The detection assembly comprises one or more energy discriminating (ED) detectors and/or one or more energy integration (EI) detectors that receive high frequency electromagnetic energy emitted by the one or more high frequency electromagnetic energy sources. The data acquisition system (DAS) is operably connected to the one or more ED detectors and/or the one or more EI detectors. The computer is operably connected to the DAS.

    摘要： A diagnostic imaging system in an example comprises a high frequency electromagnetic energy source, a detector, a data acquisition system (DAS), and a computer. The high frequency electromagnetic energy source emits a beam of high frequency electromagnetic energy toward an object to be imaged and be resolved by the system. The detector receives high frequency electromagnetic energy emitted by the high frequency electromagnetic energy source. The DAS is operably connected to the detector. The computer is operably connected to the DAS and programmed to employ an inversion table or function to convert N+2 measured projections at different incident spectra into material specific integrals for N+2 materials that comprise two non K-edge basis materials and N K-edge contrast agents. N comprises an integer greater than or equal to 1.
