1. A method for scatter correcting projection data generated by an imaging system, comprising: generating, via a distribution calculator, a plurality of scatter distributions based on geometric models having different object to detector distances; determining, via a distance determiner, an imaged object to detector distance; identifying, via a scatter selector, a scatter distribution of the plurality of scatter distributions having a object to detector distance that corresponds to the imaged object to detector distance; and employing the identified scatter distribution to scatter correct projection data corresponding to the imaged object.
