description	A method, apparatus, system, and computer program product for using an invalidity matrix, iterative reconstruction and reprojection to generate a two-dimensional image. The method includes acquiring projections through an a dental anatomy, calibrating the acquired projected images, estimating a geometry of the tomosynthesis system, determining an invalidity matrix for each acquired projection image, removing contributions of marker particles to the acquired projection images, constructing a starting volume for reconstruction, performing an iteration process for iteratively updating the starting volume, and reprojecting a final reconstructed volume to obtain a final two-dimensional image.
