CT scanning

3D computer tomography

CT scanning is x-ray scanning in 3D also called computer tomography. The technology is ideal for part verification and material analysis, as both inner and outer dimensions are documented.

With CT scanning it is possible to inspect cavities, channels, and other hidden details as well as analyze interactions between mounted parts.

3D computer tomography works by placing a part in front of an x-ray source which rotates 360º.

While the part is rotating, cross-sectional x-ray images are captured on a detector panel, and by using advanced software, the images are combined into a 3D model.

CT scanning is primarily used for quality control and part verification, material analysis, and analysis of electric components and assembled parts.

At Zebicon we offer services within CT scanning of smaller parts up to Ø200 mm. Furthermore, we are distributor of the CT scanner series ZEISS METROTOM.


Belden Cekan A/S uses CT scanning to document and validate parts in the development department, where they look at geometries, positioning and contact elements.

With a ZEISS METROTOM computer tomograph all dimensions can be measured and inspected with a single scan. Additionally, it is possible to measure multiple components simultaneously in the CT scanner, depending on the size of the parts.

Furthermore, extra dimensions can be inspected at any given time by using the generated data to do additional analysis. By comparing the scanned data to CAD data, a color plot is made. This gives a visual overview of the part’s dimensional precision.  

The particular strength of the ZEISS METROTOM is, that the measuring results are traceable and meet the current metrology standards. 

The ZEISS METROTOM series offer a broad variety of CT scanners. You can find systems with great usability and small footprint, as well as advanced CT scanners for the most demanding measurements.

With more than 10 years on the market, the METROTOM systems are based on a well proved technology, and is a measurement method acknowledged by the industry.

All METROTOM CT scanners are delivered with GOM Volume Inspect. This software is a powerful tool, which provides many opportunities for the following inspection and analysis.
