Classification: CPC G | IPC G

Claim 17:
18. A system for enhanced security threat detection, the system comprising:
a stationary x-ray source configured to irradiate a target with source x-rays having an end-point energy of at least 88 keV during an irradiation period;
a motion enablement feature configured to enable motion of the target with respect to the stationary x-ray source during the irradiation period;
a set of energy-resolving detectors configured to detect resulting x-rays received from the target resulting from the irradiation during the irradiation period and to produce signals representing an energy spectrum of the resulting x-rays;
an image generator configured to generate an image of an interior of the target based on the detected, resulting x-rays; and
an analyzer configured to:
analyze the signals for characteristic x-ray fluorescence that can be emitted from lead potentially present in the target;
provide an indication, based on the signals, of a probability of lead ammunition being present in the target;
perform analysis of the image for an indication of a weapon; and
output an indication of likelihood of a security threat in the target based on the analysis of the image for the indication of a weapon and on the probability of lead ammunition being present.
