<p>A method for reconstructing an image, including obtaining (1401) projection data using an X-ray detector and one of a cone-beam X-ray generator and a fan-beam X-ray generator, filtering (1402) the obtained projection data using a ramp-based filtering function to generate filtered projection data, weighting (1402) the filtered projection data to compensate for redundant projection data, and reconstructing (1403) the image by back-projecting the weighted projection data along a radial path.</p> |
