Computed Tomography (CT) is a well established method for non-destructive reconstruction of an object's interior structures. It is especially well suited for use with e.g. light metal alloys, injection molded plastic components or composite materials. The CT volume data can either be evaluated manually or automatically through the use of image processing software.
Recently helical CT has become available for use in industrial quality testing of light alloy cast parts. This paper discusses the use of helical CT as an additional tool for inline inspection in a production environment.
