摘要:
Embodiments of the disclosure generally set forth techniques for adjusting an estimate of scattered radiation of a target object. One example method includes generating a plurality of radiographic projections, selecting a first radiographic projection and a second radiographic projection of the target object from the plurality of radiographic projections, forming first estimates of scattered radiation in the first and second radiographic projections, applying the first estimates of scattered radiation to the first and second radiographic projections to generate a modified first radiographic projection and a modified second radiographic projection, comparing the modified first and second radiographic projections to generate correction modules, and applying one of the correction modules to a first subset of the plurality of radiographic projections and another of the correction modules to a second subset of the plurality of radiographic projections.
