摘要

Methods and/or apparatus for iteratively reconstructing a 3-dimensional volume for an object captured with radiographic imaging that includes an electronic sensor, exemplary methods can be performed at least in part on a computer, can include receiving a 3-dimensional volume data set generated from imaging an object; identifying a set of intra system components corresponding to system components used to capture images of the object, where the intra system components include at least an x-ray source within system components configured to be placed before the object; representing x-ray emission characteristics of the x-ray source as a function of angle and energy; using the 3D emission characteristics to simulate the forward projection of x-ray photons to generate a primary image and/or a scattered image; and using the primary image and/or the scattered image to reconstruct an improved 3-dimensional volume data set.
