Patent number: 11867645Abstract: In one embodiment, a system and a method for inspecting a substance to detect and identify predetermined foreign element(s) in the substance. The foreign element may carry X-ray responding material compositions, emitting X-ray signals in response to primary exciting X-ray or Gamma-ray radiation. The inspection is performed during a relative displacement between the substance and an inspection zone, defined by an overlap region between a solid angle of emission of an X-ray/Gamma-ray source and a solid angle of detection of X-ray radiation, along a movement path, as the substance moves along the movement path, the detected X-ray radiation includes X-ray response signals from successive portions of the substance propagating towards, through, and out of the overlap region. Measured data indicative of X-ray response signals is analyzed to identify a signal variation pattern over time indicative of a location of at least one foreign element carrying an X-ray responsive marker.Type: GrantFiled: October 18, 2019Date of Patent: January 9, 2024Inventors: Yair Grof, Dmitrijs Docenko, Mor Kaplinsky, Haggai Alon, Yifat Bareket, Michal Firstenberg, Avital Trachtman, Nachum Holin, Nadav Yoran
