(NSI: Rogers, MN) -- North Star Imaging (NSI) has developed a groundbreaking industrial X-ray technology, 4-D X-ray computed tomography, which NSI calls “4D CT.” NSI’s patent-pending product is considered the future of industrial 3-D X-ray inspection.

4-D X-ray CT allows users to reconstruct a complete 3-D CT model that includes time and motion, creating a truly dynamic volumetric dataset. Because this is an X-ray CT process, both the internal and external structures of an object are obtained. This technology makes it possible to study form, structure, and now function.

4D CT inspection is revolutionary for in situ testing applications such as compression, traction, and similar processes. The technology also allows users to evaluate the effects that temperature or chemicals have on an object over a period of time. Additionally, studies in hydrodynamics, process and quality, reverse engineering, failure analysis, and mechanical motion can benefit from 4D CT. For example, users can visually slice through a 3-D CT scan of a gear assembly and evaluate how the internal gears interact with each other during movement.

North Star Imaging is currently offering this nondestructive testing technology in both its X-ray CT systems—XView CT—or as an upgrade to almost any existing X-ray system, regardless of the manufacturer.

4D CT is often application-dependent; contact NSI to discuss if 4D CT can fit into your inspection process.
