One aspect relates to deriving at least one first X-ray fluorescence
visualization, image, or provided information substantially within an at
least some matter of an at least a portion of an at least one individual
at least partially as a result of directing an at least one first applied
high energy photon and/or particle having an at least one first input
energy towards the at least some matter of the at least the portion of
the at least one individual. The aspect comprises deriving at least one
second X-ray fluorescence visualization, image, or provided information
substantially within the at least some matter of the at least the portion
of the at least one individual at least partially as a result of
directing an at least one second applied high energy photon and/or
particle having an at least one second input energy toward the at least
some matter of the at least the portion of the at least one individual.
The aspect comprises deriving an at least one combined X-ray fluorescence
visualization, combined image, or combined provided information at least
partially by combining the at least one first X-ray fluorescence
visualization, image, or provided information with the at least one
second X-ray fluorescence visualization, image, or provided information.
