Claim One:
1. A method for generating an improved image of an object which is substantially free of artifacts induced by missing data comprising the steps of: a) performing a computed tomography (CT) image acquisition of the object using a cone-beam traversed over an actual scan path to acquire actual CT data which is incomplete and has missing data; b) reconstructing an initial image of a volume of interest (VOI) using the actual CT data, the initial reconstructed image having artifacts attributable to the missing data; c) reprojecting the reconstructed image of the VOI onto a virtual scan path to at least acquire virtual data corresponding to the missing data; and d) reconstructing an improved image of the VOI using the actual CT data and the virtual data, the improved reconstructed image having reduced artifacts compared to the initial reconstructed image of the VOI.
