Multi-modal scanner with metal detector for defining X-ray scan region of a human body

Abstract

Multi-modal scanner with metal detector for defining an X-ray scan region of a human body with a metal object includes an X-ray source; adjustable collimator outputting a fan-shaped X-ray beam from the X-ray source; an X-ray detector detecting the X-ray beam after passing through a human body; a metal detector adapted to identify an area with the metallic object; and a processor controlling the X-ray source, the adjustable collimator and the metal detector, and changing an aperture of the collimator to limit the fan-shaped X-ray beam to the identified area of the human body. Visual indicators (LEDs) are on a frame of the scanner for indicating the area of the human body with the metallic object. The collimator includes two lead plates that are moved vertically automatically upon detection of the metallic object to direct the fan-shaped X-ray beam to only the area of the human body with the metal.
