1. A non-transitory computer-readable medium configured to store instruction sets which, when executed by a processor of a computer system, cause the processor to form a corrected estimate of scattered radiation in a radiographic projection of a target object, the computer readable medium comprising: one or more instruction sets that directs the processor to perform the actions of generating at least one radiographic projection of the target object; forming a first scatter correction estimate of the radiographic projection, wherein the first scatter correction estimate includes scatter substantially from the target object and is based on a first segment of the radiographic projection; forming a second scatter correction estimate of the radiographic projection, wherein the second scatter correction estimate includes scatter substantially from one or more adjacent objects and is based on a second segment of the radiographic projection; and generating the corrected estimate of scattered radiation by combining the first scatter correction estimate and the second scatter correction estimate.
