ABSTRACT:
A method includes generating a plurality of scatter distributions based on geometric models having different object to detector distances, determining an imaged object to detector distance, and identifying a scatter distribution of the plurality of scatter distributions having a object to detector distance that corresponds to the imaged object to detector distance. The method also includes employing the identified scatter distribution to scatter correct projection data corresponding to the imaged object. Another method includes generating an estimate of wedge scatter by propagating a predetermined wedge scatter profile through an intermediate reconstruction of an object; and employing the estimate to wedge scatter correct the projection data.
