Abstract
A method for image reconstruction may include obtaining projection data Dgenerated by an imaging device by scanning an object at first angles, wherein the first angles may be a subset of second angles. The second angles may include at least short-scan angles for a system to conduct image reconstruction. The method may also include generating an image Fbased on the projection data D. The method may also include determining, based on the image F, projection data Dcorresponding to third angles that are a subset of the second angles and different from the first angles. The method may also include generating a final image associated with the object by performing an iteration process including one or more iterations using initial data including the image F, the projection data D, and the projection data D.
