SYSTEM AND METHOD FOR INSPECTING CONTAINERS FOR TARGET MATERIAL

摘要

A method for automatically inspecting a container for a target material using a computed tomography (CT) scanning system includes performing an initial radiographic scan of the container. Based at least partially on projection data generated during the initial radiographic scan, at least one location within the container is identified that requires CT inspection. A dual energy CT scan of the at least one identified location within the container is performed based on a single energy algorithm or a dual energy algorithm. The dual energy CT scan includes a low energy scan of the at least one identified location and a high energy scan of the at least one identified location. Based on dual energy scan information generated during the dual energy CT scan, a determination is made to confirm or clear an alarm corresponding to the at least one identified location within the container.
