A method for the reduction of motion artifacts in CT imaging, the method including the steps of: (a) reconstructing from the raw CT data an initial estimate of the object of interest; (b) estimating the pose of the object at each projection angle; (c) undertaking a motion-corrected reconstruction from the measured projections, accounting for the pose changes estimated in (b) by employing a modified source/detector orbit that accounts for the object motion; (d) iterating steps (b)-(c) until a predetermined convergence criterion is met; and (e) making a final reconstruction of the required image size using the pose estimates obtained in the previous steps.
