Abstract
A method for image reconstruction may include obtaining projection data D0 generated 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 F1 based on the projection data D0. The method may also include determining, based on the image F1, projection data D1 corresponding 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 F1, the projection data D0, and the projection data D1.
