METHOD AND APPARATUS FOR DIRECT RECONSTUCTION IN TOMOSYNTHESIS IMAGING

A technique for directly reconstructing three-dimensional images acquired in tomosynthesis imaging is provided. The method allows for pre-processing a set of projection images based upon the acquisition geometry prior to direct reconstruction of the projection images. Furthermore, the technique allows for post-processing the reconstructed image data as desired to improve image quality. If desired the direct reconstruction process may be iterated a set number of times or until a desired threshold criteria is met, such as regarding image quality.
