Micro-Computed Tomography (Micro-CT)
Micro-Computed Tomography (Micro-CT) is a high-resolution, non-destructive 3D imaging technique that uses X-rays to visualize and quantify the internal structure, porosity, density distribution, and micro-architecture of materials and biological systems. By reconstructing the full sample volume into three-dimensional datasets, Micro-CT enables detailed examination of internal features without sectioning or damaging the specimen.
At Materials Metric, Micro-CT is used to analyze internal defects, cracks, voids, interfaces, and spatial organization in biomaterials, tissue scaffolds, additively manufactured components, composites, foams, devices, and engineered materials. This capability is essential for research and development, failure analysis, preclinical studies, additive manufacturing evaluation, and quality control where internal structure directly governs performance and reliability.
Uses of Micro-CT
Micro-CT provides powerful information such as:
- Internal defects (voids, cracks, inclusions)
- Porosity and pore interconnectivity
- Density gradients and structural uniformity
- Layer quality in 3D-printed materials
- Fiber orientation and composite integrity
- Bone structure, mineral density & tissue morphology
- Coating thickness and delamination
- Non-destructive failure analysis
It is one of the most versatile tools for structural evaluation across materials, devices, and biological systems.

Sample Analysis Process
1. Sample Submission & Study Design
We review:
- Material type (polymer, ceramic, metal, composite, tissue, scaffold)
- Required voxel resolution
- Analysis goals (porosity, defects, density, structure, integration, etc.)
2. Sample Preparation
Micro-CT is non-destructive, so most samples require minimal preparation.
For optimal results:
- Samples are mounted to minimize movement
- Moisture-sensitive materials may be stabilized or sealed
- Biological tissues may require contrast agents
3. Micro-CT Scanning
High-resolution X-ray imaging generates:
- Full 3D reconstructions
- Slice-by-slice images
- Density maps and internal morphology
4. Image Processing & Quantitative Analysis
We extract:
- Porosity (%), pore size & connectivity
- Defect size & distribution
- Wall thickness and dimensional metrics
- Density gradients
- Fiber orientation maps
- Morphometric parameters for bone or tissue
- 3D visualization models
5. Reporting
Clients receive:
- 3D renderings & volume reconstructions
- Quantitative datasets
- Annotated cross-sectional views
- Interpretations aligned to R&D or regulatory goals
- Recommendations for material or design optimization
