Claim One:
1. A CT system comprising: a rotatable gantry having an opening for receiving an object to be scanned; an x-ray source coupled to the gantry and configured to project x-rays through the opening; a generator configured to energize the x-ray source to a first kVp and to a second kVp to generate the x-rays, wherein said first kVp is different than said second kVp; a detector having pixels therein, the detector attached to the gantry and positioned to receive the x-rays; and a computer programmed to: acquire a first view dataset and a second view dataset with the x-ray source energized to the first kVp and second kVp respectively; generate a reference sinogram from at least the first view dataset and the second view dataset; interpolate the first and second view datasets to generate interpolated pixels in an interpolated view dataset at the first kVp, using at least two pixels from each of the first and second view datasets and the reference sinogram to generate each interpolated pixel in the interpolated view dataset; and generate an image of the object using the interpolated view dataset.
