Using a CT Scanner for an Industrial Job These 3-D imaging devices and
has found a new home in the world of manufacturing, including metalcasting, and is opening up myriad opportunities never before available. Computed tomography (CT)

is now commonly used in various industrial metrology settings, both in the lab and online or inline for prod- uct evaluation and packaging integ- rity assessment. The main advantage is that it allows the inspection of a part’s interior structure or a pack- age’s closure functionality without causing any harm or destruction to the objects themselves, which can be of great value to buyers of castings. Industrial CT scanners utilize
ntil recently, the technol- ogy of CT imaging was only available for use in medical settings. Over the last several years, it
the same type of technology as CT scanners in hospitals and doctors’ offices—taking multiple readings from various angles and convert- ing the CT gray-scale images into voxel-based 3-D point clouds. Once the CT scanner generates the point cloud, a specialist can gener- ate a CAD-to-part comparison map, construct a 3-D model of the part, or reverse engineer the part to suit their needs. Industrial scanners offer a
multitude of advantages, such as: obtaining internal structure of an object nondestructively, validat- ing extremely accurate internal dimensions, allowing comparison to reference models, no shaded zones, compatibility with all shapes and sizes, no post-processing work and extremely high-resolution imaging.
long-range scanners serve a wide range of industries and help assure they are performing the highest level of testing and accuracy possible. A few of the diverse industries cur- rently using this technology and the goals sought are: • Metal castings: Used to check for air bubbles and overall porosity.
• Moldmaking: Provides a powerful inspection and measurement tool to validate precise injection molds and check structural integrity of a part.
• Automotive & aerospace: Allows engineers to do virtual testing of machinery, helps understand failures, and works as a research & develop- ment tool to analyze structure and simulate reactions. A wide range of industrial scanning equipment styles and sizes are available
