TS EN ISO 15708-1

TS EN ISO 15708-1 is a non-destructive testing standard that standardises the terminology used in computed tomography (CT). Its focus is not on test performance or acceptance criteria, but on the correct and consistent naming of CT-related concepts. As a result, it gathers both CT-specific expressions and broader technical terms that are also used in imaging and radiography.

Why CT vocabulary is treated as a dedicated terminology set

Computed tomography is an imaging technique that reconstructs the internal structure of an object from X-ray data acquired from multiple directions. In non-destructive testing, CT is used to examine internal defects, geometric features, density variations and fine internal details without damaging the specimen. The vocabulary focus of this standard supports consistent use of core terms such as reconstruction, projection, slice, resolution and related concepts, helping laboratories, manufacturers and users communicate with the same technical meaning.

What the vocabulary set covers

• CT-specific terms and definitions
• More generic concepts used in imaging and radiography
• Explanatory wording that helps refocus definitions in the CT context
• Core technical naming used to maintain terminology consistency

The document does not set requirements for how a CT system is configured, which tests are performed, or which numerical limits apply. Instead, it organises the technical language around CT and helps align some definitions to the computed tomography context. That makes it especially useful where the same word can carry different meanings across laboratories, equipment types and application areas.
