Method and system for inspection of containers

A method and system for reconstructing and segmenting an image of the contents of a container. The method includes receiving actual scan data from a scan of the container, reconstructing the actual scan data to obtain a reconstructed image, and segmenting the reconstructed image to obtain a segmented image. The method also includes deriving simulated scan data corresponding to the segmented image, calculating an error term based on a difference between the simulated scan data and the actual scan data, and determining whether a criterion is satisfied. The method further includes using the error term to produce a modified reconstructed image and repeating the preceding steps with the modified reconstructed image substituted for the reconstructed image if the criterion is not satisfied, and outputting information from the segmented image if the criterion is satisfied.
