1. An imaging system comprising: a radiation source configured to project radiation toward an object to be scanned; an energy discriminating detector assembly having a plurality of detector elements and configured to detect radiation emitted by the radiation source and attenuated by the object to be scanned; and a computer programmed to: count a number of photons detected by each detector element and associate an energy value to each counted photon; determine a material composition of a CT view from the number of photons counted and the energy value associated with each counted photon; apply a weighting to the CT view based on the material composition of the CT view; and reconstruct an image with differential weighting based on the weighting of the CT view.
