An X-ray inspection system generates a two-dimensional (2D) transmission image by projecting X-rays through an object from a single direction. This is the same principle used in medical radiography (health check X-rays) and airport baggage screening. In contrast, a Computed Tomography (CT) system captures multiple X-ray images of an object from various angles and uses a computer to reconstruct them into a three-dimensional (3D) image.
While medical CT scanners typically rotate the X-ray source and detector around the patient, most industrial CT systems rotate the object being inspected. The predominant method in industrial CT is Cone-Beam CT (CBCT), which allows for the acquisition of a complete 3D volumetric dataset with a single 360-degree rotation.
