Abstract
Embodiments of methods and/or apparatus for 3-D volume image reconstruction of a subject, executed at least in part on a computer for use with a digital radiographic apparatus can obtain a 3D volume reconstruction or projection image by generating a first-filtered set of projection images from a plurality of 2-D projection images taken over a range of scan angles and a different second-filtered set of projection images from the plurality of 2-D projection images. Then, for example, a first 3-D volume image of the subject from the first-filtered set of projection images and a second 3-D volume image of the subject from the second-filtered set of projection images can be combined using different weighting combinations in at least two corresponding portions to generate the 3-D volume image of the subject.
