Title:
SYSTEMS AND METHODS FOR IMAGE RECONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2019/105460
Kind Code:
A1
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 F 1 based on the projection data D 0. The method may also include determining, based on the image F 1, projection data D 1 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 D 0, and the projection data D 1.
