System And Method For Detection And Identification Of Foreign Elements In A Substance

A system for detecting and identifying at least one predetermined foreign element in a substance, the system comprising:

• a measurement device comprising:
• a radiation source assembly comprising at least one source of X-ray or Gamma-ray radiation, each source being configured to generate X-ray or Gamma-ray radiation having predetermined properties and a predetermined solid angle of radiation emission to excite a portion of the substance located in a region within said predetermined solid angle to cause an X-ray response of said portion;
• a detection assembly comprising at least one detector having a solid angle of radiation detection overlapping with said solid angle of radiation emission, each detector being configured and operable to detect an X-ray radiation propagating within a solid angle of radiation detection and generate measured data indicative of the detected X-ray response;
• the measurement device being configured and operable such that the X-ray radiation being detected during a relative displacement between the substance and at least one of the radiation source assembly and the detection assembly along a movement path is indicative of a time variation of the X-ray response of the substance;
• and
• a control unit configured and operable for data communication with said detection assembly to receive and analyze the detection data, the control unit comprising a signal processor configured and operable to identify in said measured data a pattern of a signal variation over time indicative of a location of at least one foreign element carrying an X-ray responsive marker in said substance.
