摘要：
A method and system for image reconstruction are provided. A projection image of a projection object may be obtained (420). A processed projection image may be generated based on the projection image through one or more pre-process operations (430). A reconstructed image including an artifact may be reconstructed based on the processed projection image (440). The artifact may be a detector edge artifact, a projection object edge artifact, and a serrated artifact. The detector edge artifact, the projection object edge artifact, and the serrated artifact may be removed from the reconstructed image (450).
