A method and apparatus for detecting objects in computed tomography (CT) data are shown. Specifically, the system can identify objects that contain liquids, if desired. A subregion that encloses an object is defined, and a top surface of the subregion is identified. Volume elements at the surfaces of the object are identified. If a ratio of top surface volume elements to the total number of surface volume elements is determined. If that ratio exceeds a predetermined threshold, then the object can be identified as including a liquid.
