1. A system for generating an image of an object using data acquired in a helical scan, said system comprising an x-ray source and a detector array, said system configured to:

  • determine a helical weighting function;

    determine a standard deviation ratio of reconstructed images with and without helical weighting;

    identify a filter coefficient based at least in part on the determined standard deviation ratio; and

    apply the identified filter coefficient to the data.
