ABSTRACT:
An x-ray CT scanner acquires projection data from a series of projections during a scan of a patient's chest Movement of the patient's chest due to respiration is also sensed during the scan and this acquired motion data is employed along with an warping function which models chest motion to calculate factors which correct the acquired projection data and reduce motion artifacts in an image produced by back projecting the acquired projection data.
