Abstract
An x-ray fan beam is caused to impinge upon an object, such as airport luggage or jars of food, as the object moves translationally through the fan beam; after passage through the object, the x-rays are made to impinge upon an x-ray transmissive detector housing containing a gaseous detecting medium, a power electrode and a plurality of signal electrodes. The power electrode and the signal electrode are maintained at different voltage levels so that electrons and/or ions generated by the interaction of the gaseous detecting medium and the x-rays, drift toward the electrodes thereby producing an electrical current which can be sensed, analyzed, and used, for example, to generate an image or to indicate the presence of foreign matter.
