Abstract
An imaging system includes a radiation source (, T, T, T) that rotates about an examination region and emits radiation that traverses the examination region. The radiation source (, T, T, T) emits radiation having an energy spectrum that is selectively alternately switched between at least two different energy spectra during an imaging procedure. The system further includes an energy-resolving detector array (, D, D, D) that detects radiation traversing the examination region. The energy-resolving detector array (, D, D, D) resolves the detected radiation over at least two different energy ranges and produces energy-resolved output signals as a function of both emission energy spectrum and energy range. The system further includes a reconstructor () that performs a spectral reconstruction of the energy-resolved output signals. In another embodiment, the detector array () includes a photon-counting detector array ().
