Container inspection is categorized into three stages. In the initial stage, large-size X-ray DR (digital radiography) is used to inspect full containers sitting on their trailers. If that inspection identifies uspicious cargo, the trailer and container are relocated to a nearby inspection position for opening the container and inspecting all cargo inside. In the second stage, small-size X-ray DR equipment is used to inspect each cargo. If a suspicious cargo is detected here, it is then opened, the contents are extracted and checked by manual procedure. For cargoes that cannot be opened, such as religious statues or works of art such as sculptures, third-stage inspections are conducted using an X-ray (computed tomographic) scanner. Hitachi, Ltd. is the only manufacturer in the world that can provide the equipment needed in all three cargo-container inspection stages.
