One aspect relates to capturing one or more tomographic-type Compton scattering based visualizations, images, or provided information of an at least some matter of at least a portion of an individual based at least partially on Compton scattering of an at least one X-ray being applied to the at least some matter of the at least the portion of the individual. Another aspect relates to deriving an at least one material characteristic distribution function that substantially fits at least some data obtained at least partially by scattering of an at least one applied X-ray within at least some matter of at least a portion of an individual to form at least one Compton scattered X-ray.
