ABSTRACT:
The present invention provides a digital system including circuitry for imaging items passing on a conveyor belt through an X-ray fan beam. The circuitry of the present invention enables detection of the items as soon as the X-ray beam is pierced and an image of the items is maintained on a monitor following removal of the items from the X-ray beam. This enables detection of all items entering the X-ray beam, and subsequent inspection of the items.
