On the roadmap · planned
Micro-CT for additive and cast parts.
X-ray micro-computed tomography rotates a part in an X-ray beam and reconstructs its full internal volume from hundreds of projections. It sees porosity, voids, and inclusions in three dimensions, and it is on the Sondera roadmap so the same defect analysis and reporting can run on volumetric data.
The modality
A full 3D view of what is inside.
In micro-CT, a part sits between an X-ray source and a detector and rotates a fraction of a degree at a time. At each angle the detector records a projection, a shadow image of how much the material absorbs. Hundreds or thousands of these projections are combined by reconstruction into a stack of cross-sectional slices: a complete 3D volume of the part at micrometer resolution.
Because every voxel carries a density value, internal features stand out on their own. A pore is a low-density spot, an inclusion a high-density one. There is no echo to interpret; the geometry is there to measure directly.
What it measures
What tomography reveals.
Porosity and voids
Gas pores and shrinkage voids in castings and additive parts, counted, sized, and located in 3D.
Inclusions and density
High- and low-density inclusions and local density variation, straight from the reconstructed voxels.
Internal geometry
Wall thickness, channels, and lattice structures measured non-destructively, even where no probe can reach.
Cracks and delaminations
Volumetric cracks and layer defects in additive parts, seen through the full thickness.
How it works
From projections to a signed-off report.
Rotate and project
The part rotates in the X-ray beam while the detector records a projection at each angle.
Reconstruct the volume
Projections are reconstructed into a 3D stack of density slices at micrometer resolution.
AI defect analysis
Models segment pores, voids, and inclusions from the volume and separate real defects from artifacts and noise.
Quantify and classify
Each indication is sized, located, and classified with confidence, and porosity is quantified across the part.
Map to a decision
Results are compared against acceptance criteria and assembled into a traceable report.
Why micro-CT
Nothing else sees the whole volume.
Where terahertz and ultrasound infer defects from signals, CT measures the internal geometry directly, in three dimensions. For complex additive and cast parts it is often the only way to qualify what is inside.
- True 3D: the full internal volume, not a surface or a line
- Direct measurement of geometry and density, not an inferred echo
- Micrometer resolution on small, complex parts
- Ideal for additive manufacturing qualification
- One scan supports metrology and defect analysis together
Where it fits
Built for complex, high-value parts.
CT completes the picture: terahertz and ultrasound for fast, in-line or field inspection, micro-CT for the definitive 3D qualification of high-value parts.
How it joins the platform
Volumetric data, the same decision layer.
Micro-CT is planned, not yet live. It brings a different kind of data, a 3D volume rather than a time-domain signal, but the goal is the same: find the defects, size them, and map them to a decision with confidence and a traceable record. The reconstruction and 3D segmentation are the new front end; the detection and reporting layer is shared with the rest of the platform. Tell us if volumetric inspection is a priority for you.
