A tomographic imaging apparatus is provided for generating images. The tomographic apparatus includes a computer programmed to access a data sinogram representative of the image, reconstruct the image, divide the image into a plurality of sub-regions, define a region of interest including at least one sub-region, reprojecting a region of interest or a complement of the region of interest to generate a region of interest sinogram or a sinogram representative of the complement of the region of interest and reconstructing a resultant sinogram using iterative methods to generate an image.
