Definition
Industrial CT Inspection — What It Measures and What It Cannot
Industrial computed tomography (CT) uses a focused X-ray beam and a flat-panel detector to acquire up to 3,600 2D projection images of a rotating part. A reconstruction algorithm (FDK cone-beam) generates a 3D voxel volume representing the material density distribution throughout the entire component — external and internal surfaces included.
The TomoScope XS Plus integrates a tactile/optical multi-sensor CMM frame with the CT module, enabling both CT-based and contact-probe measurements in a single setup. This removes the need for a separate fixture and eliminates re-alignment error between CT and CMM measurements.
CT inspection does not substitute for surface optical measurement where feature access is not the limiting factor. The correct system is selected based on: part material density, feature location (internal vs. external), required dimensional uncertainty, and whether the test is destructive or non-destructive.
Method Comparison
Data Output
CT Cross-Section Analysis
The CT reconstruction volume is interrogated in any plane — axial, coronal, or sagittal — without physical sectioning. Each cross-section is a grayscale density map where material, voids, and internal features are distinguishable by grey value. Features are measured directly from the volume using GOM Volume software.
Axial (Z-plane)
Horizontal slices through the part — standard for bores and channels
Coronal (Y-plane)
Front-to-back cross-sections — ideal for wall thickness gradients
Sagittal (X-plane)
Left-to-right views — reveals asymmetry and fill-related defects

Inspection Scope
What the TomoScope XS Plus Measures
Six core inspection disciplines — each with defined methodology, output format, acceptance standards, and traceability documentation.
Non-Destructive Testing
Inspect internal geometry without cutting, sectioning, or altering the part in any way.
Industrial CT is the only inspection method that provides complete 3D data of internal features — voids, inclusions, delaminations, and cracks — while preserving the part for further use or production. The TomoScope XS Plus generates a full volumetric dataset from 1,000+ X-ray projections taken through a 360° rotation.
