Abstract
A method of preprocessing cone beam projection data acquired using a dual x-ray focal spot acquisition approach in which projection data is acquired over a series of angular positions of the CT scanner about a body, and wherein at least two angularly displaced x-ray sources (focal spots) are alternately activated as the scanner rotates orbitally around the body. The pre-processing involves a resampling of the projection data from the first and second focal spots to a new virtual sampling point part way between the first and second focal spots.
