Computed Tomography Basics
Computed Tomography (CT) is an advanced non-destructive testing (NDT) technology that utilizes computer processing to generate precise cross-sectional images of an object from a series of 2D X-ray projections. During an industrial CT scan (also known as micro-CT), the object is precisely rotated while hundreds or thousands of 2D X-ray images are acquired from various angles.
This type of imaging is called a cone-beam CT scan. Sophisticated reconstruction software then processes this series of projection images to generate a stack of cross-sectional slices (tomographic images). By compiling these slices, a complete three-dimensional (3D) volume model, composed of volumetric pixels (voxels), is created.
Normal scan vs Offset scan
In cone-beam CT normal scan, if the width of the vision image of the sample is larger than the width of the X-ray camera, you need to shoot the sample repeatedly to obtain the tomographs. The offset scan technique overcomes this limitation. By shifting the detector horizontally relative to the center of rotation, it's possible to scan objects up to nearly twice the width of the detector in a single rotation, significantly expanding the effective scanning volume and improving workflow efficiency.

RECONSTRUCTION
The image reconstruction process involves a computer generating cross-sectional images from the projection data collected by the CT scanner. This results in false and unwanted features in the image, called artifacts, which can be mitigated by software options.
Ring Artifact Reduction
Ring artifact reduction reduces concentric ring noise that occurs in tomographic images through a filtering process.

Geometric Dimensioning and Tolerancing (GD&T)
Using 3D display analysis data, you can check areas of sample structure, foreign matters, or shrinkage cavities in molding that cannot be measured by contact-type instruments. In addition, the function visualizes deviations and defect locations, facilitating sample inspection. It is suited for mold designs and inspections of shrinkage cavities in casting.
Nominal/Actual Comparison (Part-to-CAD)
Directly compare your scanned data (as-built) against the original CAD model (as-designed). This generates an intuitive, color-coded deviation map, instantly highlighting any manufacturing errors or warping with precision. Different colors can identify deviations.
Wall thickness analysis
Visualization of wall thickness analysis using CAD data and CT data is available. It is also available for errors in design values. The errors can be identified by color.
Wall thickness analysis (2D-display)
Three-dimensional images are used for the wall thickness measurement.
Material Analysis
Automated Defect & Porosity Analysis
Automatically detect, locate, and quantify the size, volume, and distribution of internal defects such as pores, voids, and inclusions. This is crucial for quality assurance in castings, additive manufacturing (AM), and composite materials. It can also calculate the percentage of defects to the sample volume. It is available in the following categories.
- Scale (circumscribed sphere)/Volume
- Surface area
- Position XYZ
- Self - Sphericity
- Spacing (distance between defects)
- Projected size XYZ
