Abstract
A method for estimating projection data outside a field of view of a scanning device, including: obtaining measured projection data by scanning an object using the scanning device; selecting a projection angle and a fan angle outside a field of view of the scanning device; determining, based on the selected projection angle and fan angle, a plurality of sinogram curves, each sinogram curve corresponding to a different image point in the object; determining a contribution value for each of the sinogram curves based on the measured projection data; and calculating estimated expanded projection data for the selected projection angle and fan angle based on the determined contribution values.
