Abstract
A method, an apparatus and a system are provided for assessing at a security checkpoint the threat status of a liquid product comprised of a bottle at least partially filled with liquid. Generally, an X-ray image of the liquid product is obtained and processed to derive a level of fill of the bottle and the threat status of the liquid product is determined at least in part based on the level of fill of the bottle. In some examples presented, an X-ray image of the liquid product is processed to derive location information associated with a meniscus formed by the liquid in the bottle and an estimated length of a path followed by X-rays through the liquid held in the bottle is used to determine the threat status of the liquid product, the length of the path being derived in part based on the location information.
