Abstract:
1. A CT system, comprising: a detection assembly capable of measuring a plurality of projection data at a same projection path that corresponds to a plurality of distinct incident energy spectra, wherein 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 one or more high frequency electromagnetic energy sources that emit one or more beams of high frequency electromagnetic energy toward an object to be imaged; a data acquisition system (DAS) operably connected to the one or more ED detectors and/or the one or more EI detectors; and a computer operably connected to the DAS and programmed to: patch missing data of the plurality of projection data at the same projection path in an incident energy spectrum of the plurality of distinct incident energy spectra.
