Claim One:
1. A method for digital radiographic image reconstruction of an object, executed at least in part on a computer, comprising: obtaining a first plurality of 2D projection images over a range of scan angles; obtaining a second plurality of 2D projection images over a range of scan angles; generating at least two statistically independent reconstructed images of a portion of an object from the first plurality of 2D projection images and the second plurality of 2D projection images; determining a material property for each of at least two materials represented in the projection images; using a conditional likelihood determination comprising the material property for said each of at least two materials and the at least two statistically independent reconstructed images to differentiate the at least two materials as a function of volume in a reconstructed image of the portion of the object; and storing the reconstructed image of the portion of the object having the at least two materials differentiated in a computer-accessible memory.
