1. A method of substantially reducing cone beam artifacts, comprising: providing a predetermined number of corrected images based upon a first image containing cone beam artifacts and a second image including correction that is scaled by a scaling factor at a corresponding one of the predetermined number of distinct values; isolating the cone beam artifacts in a plurality of third images from each of the corrected images; determining a cone beam artifact metric for each of the third images; and selecting an optimal one of the distinct values for the scaling factor based upon the cone beam artifact metric.
