A system for detecting embedded objects in a specimen that includes a transport system effecting movement of the specimen relative to an imaging zone along a transport path. The system also includes detector systems arranged to operably image the specimen in the imaging zone. Each detector system includes an emitter, detector, and a primary axis defined between the emitter and detector and that crosses the transport path. Energy from the emitter is directed along the primary axis and transmitted to a unique detector producing a succession of images as there is movement of the specimen relative to the imaging zone. The system further includes a computer system operably connected to the detector systems to receive and combine the succession of images producing a plurality of image slices that are combined as a representation of the specimen for use in detecting embedded objects in the specimen.
