Non-destructive testing of a bike helmet

One of our clients from 2012/2013 contacted us with a private testing request: he fell with his mountain bike hitting his head very hard on a rock, causing serious whiplash. He wanted us to inspect possible damage to his helmet in the impact location. We performed two scans for this, one full-helmet scan and one …

Analysis method for porous concrete

Often it is necessary to understand the 3D porous structure of materials, but the analysis can be complicated in 3D due to the high interconnectivity of pores. A relatively simple analysis is the foam structure analysis which seperates connected pore spaces making the analysis more realistic and comparable between samples, to understand the real pore …

Failure analysis

This video shows the 3D morphology of a crack in steel. This is used for failure analysis in various industries and for all kinds of products and materials. Such information (as crack morphology in 3D) is useful for safety investigations, lifetime prediction, failure root cause analysis for future prevention, and also for legal disputes. Video …

Biomedical CT scans

Any medical CT data can be processed, visualized and analyzed in detail at our facility. Got a medical CT data set and need something MORE? No problem, we do it. All we need is the DICOM or image stack with XYZ slice and pixel spacing. We also handle 3D data from serial block face imaging, …

How to crop a volume

CT data is big. Sometimes you need to share data more easily, for example using file transfer services but 10 Gb just doesnt work. Here is a video showing how to select a region of interest and export it to a new volume of less than 2Gb, with a VGL file associated with it so …
