Abstract
A computed tomographic imaging system is provided for generating computed tomography images. The computed tomographic system includes a processor configured to access image data encoding X-ray projections at a detector position and a plurality of X-ray source beam focal spot positions and to align pixel values for the projections in a direction of deviation of the positions. The processor is also configured to determine a correction factor for at least one of the projections based upon the aligned pixel values and upon a sum of the projections and to correct the pixel values for the at least one of the projections based upon the correction factor.
