Micro nano CT machineMicro nano computed tomography (CT) is an advanced imaging device that combines micro nano focal X-ray sources with high-precision detection systems. Its core breakthrough lies in increasing the resolution of traditional CT to the micrometer to nanometer level, becoming a key tool for microstructure analysis in fields such as materials science, biomedical science, and geological archaeology. It penetrates the sample by emitting X-ray beams with micro nano focal points (usually less than 1 micron in diameter), uses detectors to receive transmission signals from different angles, and combines computer tomography reconstruction algorithms to generate three-dimensional images.

　　Micro nano CT machineIts main functions are as follows:

1. Non destructive 3D internal structure imaging

Core function: Obtain complete three-dimensional structural information inside the sample without cutting or damaging it. This is crucial for precious, rare, or indestructible samples such as fossils, artifacts, electronic devices, and biological tissues.

Advantages: Avoiding information loss and human damage caused by traditional slicing methods.

2. High resolution 3D reconstruction

Function: By collecting hundreds to thousands of two-dimensional X-ray projection images from different angles, using computer tomography (CT) reconstruction algorithms (such as filtered back projection), generate a three-dimensional volume dataset (Voxel Data) of the internal structure of the sample.

Accuracy: The resolution is much higher than that of conventional medical CT, and it can clearly distinguish fine structures such as pores, cracks, particles, fibers, and blood vessels at the micrometer level.

3. Internal defect and damage detection

Function: Accurately detect and locate defects inside materials or components, such as:

Pores and inclusions: in metals, ceramics, and composite materials.

Cracks and delamination: in welded parts, composite materials, and coatings.

Fracture and fatigue damage: In the study of material mechanical properties, in-situ tensile/compression experiments can be conducted to observe the initiation and propagation of cracks in real time.

4. Geometric dimension and morphology analysis

Function: Accurate geometric measurement and morphology analysis of reconstructed 3D models:

Measure the dimensions, wall thickness, volume, and surface area of complex internal structures.

Analyze the particle size distribution and shape factor (sphericity, aspect ratio) of the particles.

Measure the porosity, pore size distribution, connectivity, and tortuosity of porous materials.

5. Composition and density analysis (qualitative/semi quantitative)

Function: Different materials have different absorption rates of X-rays, which appear as different grayscale values in CT images.

It is possible to distinguish between phases or materials of different densities in the sample (such as metal and non-metal, different alloy phases).

By analyzing grayscale values, semi quantitative density comparisons can be made to evaluate the uniformity of materials.

6. Observation of dynamic and in-situ processes

Function (high-D device): Equipped with a dedicated sample stage, it can apply external loads (force, heat, electricity, fluid, etc.) to the sample during CT scanning, achieving in-situ or four-dimensional (4D, 3D+time) observation.

Application: Real time observation of material deformation under stress, crack propagation, structural changes during battery charging and discharging processes, fluid flow in porous media, etc.

7. Visualization and Virtual Slicing

Function:

3D visualization: rendering the reconstructed volume data in 3D to visually display the complex internal structure of the sample.

Virtual slicing: Virtual slicing can be generated in any direction (cross-sectional, coronal, sagittal, or any inclined plane), similar to using a "virtual knife" for cutting and observing internal details.

8. Data export and further analysis

Function: Export reconstructed 3D data to a universal format (such as DICOM, TIFF sequence, STL, etc.) for:

Combined with finite element analysis (FEA) software, conduct mechanical simulations based on real structures.

Combining with 3D printing to manufacture internal structural replicas.

Conduct more in-depth quantitative analysis in professional software.
