ABSTRACT:
In accordance with an embodiment, a method of examining contents of objects comprises accelerating a plurality of electrons to a predetermined acceleration energy and colliding the accelerated electrons with a target. An object is scanned with the generated X-ray photons. First energies of X-ray photons are determined after scanning and second energies of accelerated electrons are determined after colliding with the target, and correlated. Energies of respective detected X-ray photons prior to scanning are determined based, at least in part, on the second energies of respective correlated accelerated electrons and the predetermined acceleration energy. A potential presence of suspect material is determined based, at least in part, on the first energies of respective X-ray photons after scanning and the third energies of the detected X-ray photons prior to scanning. Systems are also disclosed.
