Claim:
1. A method of reconstructing a 3-dimensional volume image of an object captured with an x-ray imaging system having an x-ray source configured to emit x-ray photons and a detector having a plurality of imaging pixels to capture x-ray images of the object, the method comprising: receiving 3-dimensional volume image data of the object; identifying components of the x-ray imaging system placed between the x-ray source and the object; calculating transmission values for a plurality of energy levels of the x-ray source, wherein each energy level is associated with a plurality of x-ray photon paths that pass through the identified components of the x-ray imaging system and impact the imaging pixels; constructing a bounding spectral curve based on the transmission values, including accepting and rejecting a plurality of simulated x-ray photons using the bounding spectral curve as a threshold; generating scattered image data based on the step of accepting and rejecting the plurality of simulated x-ray photons; and reconstructing the 3-dimensional volume image of the object using the scattered image data in combination with the captured x-ray images of the object.
