Sample size vs resolution example

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 …

Oil pump

One part of an oil pump was scanned to demonstrate the quality of 3D information, which can be used for quality inspection or reverse engineering. See images below of slice and 3D images of internal porosity. Clearly there is one very large pore (coloured in red) which is shown in slice images also. Close-up of …

Automotive casting – water pump

This example shows a water pump, with a porosity/defect analysis performed on one region of the casting. This shows how easily casting porosity can be identified and quantified (each pore has its void volume and other parameters calculated). The analyzed region has its surface data also available for output to STL format, for reverse engineering …
