Methods for performing image reconstruction that include deriving background projection data for an area outside a targeted field of view of a tomographic image, and reconstructing the tomographic image of the targeted field of view, wherein the background projection data is used in the reconstruction. Methods for selecting a reconstruction methodology that include determining a number of pixels in a reconstructed image for a first reconstruction methodology, determining a number of pixels in a reconstructed image for a second reconstruction methodology, comparing the number of pixels for the first reconstruction methodology and the number of pixels for the second reconstruction methodology, and selecting the reconstruction methodology for image reconstruction based on the comparison of the number of pixels. Imaging systems implementing these methods are also provided.
