System and method for detecting and reconstructing objects in a non-continuous stream of items in an imaging system

A controller for detecting objects moving in a first direction in a computed tomography (CT) imaging system is provided. The controller is configured to detect objects by assembling a plurality of segments based on a plurality of CT imaging slices. In response to receiving a stop request, the controller is configured to detect objects by causing the CT imaging system to cease a flow of objects, discarding the one or more of the plurality of CT imaging slices associated with a first segment and a second segment of the plurality of segments, causing the CT imaging system to move the objects in a second direction for an interruption distance in which the second direction is opposite the first direction, causing the CT imaging system to move the objects in the first direction, and reassembling the first segment and the second segment.
