摘要: A method is disclosed for providing an optimized energy bin parameter set photon-counting spectral computed tomography. In one embodiment, the includes receiving tomography data related to a plurality of bins and initial set; performing iteration steps steps. An input first step as each further adjusted calculated in preceding set.
