Digital Radiography (DR) is a real-time 2D X-ray imaging method with uses an X-ray detector instead of film. DR is quick, efficient, and effective for many routine inspections, especially when surface defects or simple internal features need to be checked. It’s ideal for inspection of a few components or as a cost-effective solution for high-throughput inspections.

Computed Tomography (CT) uses X-rays to create detailed cross-sectional images (slices) of an object, which can be reconstructed into a 3D model. This provides a complete 3D representation of the internal and external structures of an object, making it ideal for complex components and thorough defect detection. CT scans can be used to measure internal dimensions and geometries accurately.

Industrial DR and CT are used across industries for many types of parts and materials. Examples include Additive Manufacturing, Polymers, Composites, Metals/Alloys, Electronics, Batteries, Castings, Welding/Soldering, Medical Devices, Automotive Parts, Explosives & Ballistics, and Consumer Products.

NDT Methods and Analysis for DR & CT

• Detail and Dimensional Accuracy: Industrial CT provides highly detailed 3D images and is capable of precise dimensional measurements, whereas DR provides 2D images and is more suited for surface/subsurface defect detection.

• Complexity of Analysis: Industrial CT is better suited for analyzing complex internal structures of parts can components, where accuracy of conformance is critical. DR is often used for simpler, faster inspections for determining voids, cracks, contamination, and foreign material.

High-energy CT scanning is needed when dealing with large, dense, or thick objects. Lower energy X-ray and CT methods can be insufficient to penetrate the material and provide the necessary resolution and detail. North Star has 9MeV and 6MeV systems available for your large parts and complex imaging needs. Check out the various industry applications that are ideal for our High Energy MeV Scanning Services.
