Abstract:
A method for tomographic three-dimensional (3D) reconstruction of a sample including at least one object of interest, the method comprising the steps of:(a) obtaining a current set of projection images from a projection system; (b) adjusting the current set of projection images of the sample according to a priori knowledge to produce adjusted projection images; (c) using a reconstruction algorithm on the adjusted projection images to generate a 3D image; (d) further adjusting the 3D image according to the a priori knowledge to generate an adjusted 3D image; (e) applying criteria for process completion to determine whether the adjusted 3D image is adequate; and (f) if the adjusted 3D image is not adequate, then computationally creating a set of pseudo projections at the same projection angles as the current set of projection images and comparing the current set of projection images with the pseudo projection images to produce a set of new projections, wherein the new projections are input again at step (a) as a current set of projection images and steps (a) through (e) are repeated until the adequacy criteria are met.
