Claim One:
1. A method used in digital breast tomosynthesis (DBT) for image reconstruction comprising: generating projection data of a projection object using a DBT device including a radiation source and a detector; generating, by a processor, a projection image of the projection object based on the projection data; pre-processing, by the processor, the projection image to generate a processed projection image; reconstructing, by the processor, the processed projection image to generate a reconstructed image including an artifact; and removing, by the processor, the artifact in the reconstructed image, the pre-processing the projection image including segmenting the projection image to generate a segmented projection image; and the artifact including a detector edge artifact relating to a detector edge, a projection object edge artifact relating to a projection object edge, and a serrated artifact, and the removing the artifact in the reconstructed image including: removing the detector edge artifact; removing the projection object edge artifact; and removing the serrated artifact using a projection object template.
