Industrial X-ray and computed tomography (CT) for nondestructive testing are rapidly expanding, with new applications and inspection systems emerging all the time. With so many choices available, it is critical to match the right technology with your individual inspection goals. Understanding the tradeoffs between X-ray/CT system types and what works best for your specific applications will help save time and money for years to come.

One of the most important concepts to learn prior to selecting an industrial CT system is the difference between flat-panel detector cone beam CT systems (CBCT) and line-detector fan beam CT systems (FBCT). Both modalities are powerful solutions for CT inspections; however, significant performance and time trade-offs exist between them. In fact, many CT system manufacturers offer CT systems equipped with a flat-panel X-ray detector and a linear detector array. Both technologies enable powerful 3D visualization capabilities of internal features and defects, but each excels in different applications and use cases. The different use cases in conjunction with price and time differences between FBCT and CBCT make this concept critical for any prospective buyer to understand.
