1. A method of reconstructing a computed tomography (CT) image, the method comprising:

  • i) obtaining an initial CT image;

    ii) performing a reconstruction algorithm on the initial CT image to obtain a reconstructed image of the initial CT image;

    iii) using the reconstructed image to adjust one or more parameters associated with the image;

    iv) using the adjusted one or more parameters to perform the reconstruction algorithm on the reconstructed image to obtain an updated reconstructed image; and

    v) repeating steps iii)-iv), using the most-recently updated reconstructed image in each repeated step iii), and updating the same one or more parameters in each repeated step iii) until a threshold value of a predetermined characteristic is met.
