1. An image screening system, comprising: an image scanner configured to scan an object to generate a scanned image of the object and configured to photograph the object to generate a photograph of the object, the scanned image corresponding to an interior of the object, the photograph corresponding to an exterior of the object; at least one portable image viewing device; and a controller including circuitry configured to: transmit the scanned image and the photograph to the at least one portable image viewing device; trigger display of the scanned image and the photograph corresponding to the object, on a screen of the at least one portable image viewing device, the photograph being displayed at a different scale than the scanned image, the photograph being visible without being overlaid by the scanned image to enable use of the photograph to identify external features of the object not visible in the scanned image to uniquely identify the object relative to other objects that have been scanned; match the scanned image with the object by displaying its corresponding scanned image and its corresponding photograph, as selected from a plurality of other scanned images and other photographs taken from a plurality of other objects, such that the scanned image and the photograph match up with the object; and trigger display of a subset portion of the scanned image, while displaying an entirety of the photograph, on the screen of the at least one portable image viewing device when the at least one portable image viewing device is held over a subset portion of an exterior of the object, the subset portion of the exterior of the object corresponding to the subset portion of the scanned image, wherein movement of the portable image viewing device toward or away from the exterior of the object automatically adjusts a zooming level of the displayed subset portion of the scanned image.
