We scanned a wasp hive and found some interesting contents, which is a nice example of the non-destructive imaging capabilities of microCT. The 5 wasps are coloured for visual impression and all have been dead for a few months prior to the CT scan. Watch a 3D video of this example (link below the images). …

Maize is a staple food in South Africa and in Africa. One of the factors affecting the milling quality and efficiency of production is the maize hardness – in this study MicroCT was used to investigate hardness in maize kernels using full 3D information as well as a density calibration. Read the full paper here: …

Recently we scanned another brittlestar (Brooding Ophiuroid). Due to the size of the sample (25mm) it was difficult to observe small features of the specimen. This granted us the opportunity to see how CT Scanning combined with 3D printing can enhance the way we can visualize and observe the small samples and specimens. In the …

The most common misunderstanding people have the first time they use either microCT or nanoCT is how the sample size relates to the achievable resolution. In the following example I will try and provide you some insight into how these two parameters work together. To illustrate the example I scanned a packet of cigarettes at …

This work is from Jannes Landschoff, who won the best poster award for his poster “How many inside? A 3D Micro CT-Scan of Brooding Ophiuroids” at the European Echinoderms Colloquium, Portsmouth, UK in July. Jannes is a MSc student from UCT Biology. This work is still ongoing so more striking images will be loaded once …

This example puts a nanoCT scan into perspective, as the 550 nm resolution allows a field of view of up to about 1 mm, allowing the tip of a toothpick for example to be analyzed in full 3D. This is why this is also called a 3D X-ray microscope. See below some images and videos …

In this example, preliminary work was done by Prof Guy Midgley investigating the internal structures of selected South African plant leaves. One succulent and one Leucadendron laureolum leaf was scanned at different resolutions, though even higher resolution and detail is still possible. See below images of the succulent and images and a movie of the …

Non-destructive testing of consumer products is not new, with many laws protecting consumers. However, producers and suppliers do not test products unless explicity legally required. We offer simple analysis and testing for any users. In this example, we illustrate how a packet of cookies can be quickly inspected by CT scanning and X-ray imaging, with …

This example is an abalone shell with coral on top of the shell. Some of the images show the internal connected pathways in the coral.

A human skull was CT scanned, with the aim to generate a CAD file with extremely high detail. The CAD file can be used to generate a digital facial reconstruction. More about this will be included in later posts, but here we provide nice images and movies of the skull. CAD file available on request. …
