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.

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, FIB-SEM, synchrotrons, 3D handheld scanners and CMMs and many more.

This example shows some of the advanced analysis that is made possible, and highlights the potential for microCT applications in biomedical engineering studies as well, this microCT scan of a human femur was taken at 50 um. Enjoy the video and get in touch to make videos and analysis like this for your research or industrial application

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 the alignment and voxel size is maintained. Happy sharing, and send us your cropped data for processing !

Level 3 lockdown

Great news – we have opened under strict level 3 conditions from 1 June 2020. We are open for work under the following rules:

  • From June 1st, clients are advised to use the drop-off booking option to submit samples for scanning or data for analysis https://www.supersaas.com/schedule/CAF_Booking_systems/CT_Facility
  • Samples and data drives will be delivered at scheduled times only, to our facility gate and left on the floor after ringing the bell. No walk-ins allowed, times for delivery must be arranged beforehand. Sample packaging will be sprayed with alcohol spray and the package left for one day unopened. The same procedure in reverse for data and sample pickup. National and international clients are requested to use courier services, adding our phone number.
  • Students who require analysis time will be required to conduct a daily health assessment (self –evaluation) to determine if they are fit for work.
  • Only trained students to use facilities, no training or one on one assistance will be provided.
  • To adhere to social distancing, only one student will be allowed to analyse in a day on a PC. BOOKING in advance is essential.
  • Trained students with sufficient internet bandwidth may make use of the remote analysis on another PC – same booking slots necessary, arrange with us before for the login details. No support after hours is possible, if you are kicked off or make a mistake.

Foam structure analysis

In this example a nanoCT scan of a 3 mm section of rigid foam is used to demonstrate the analysis of connected pore spaces. For more technical details please contact us, the images speak “volumes” by themselves:

NanoCT of woven material

This example shows a small section of material scanned using nanoCT and analyzed for fibre thickness and angular distribution

Very short video of the CT slices: fibres

NanoCT of cardboard

One application of nanoCT scanning is to measure coating thickness of paint coatings for example. In this case a cardboard packaging material has its paint coating analyzed with a colourmap showing the thickness distribution.

This is the 4 mm sample loaded for a scan

Flower for Womens day

It was women’s day recently in South Africa so we scanned a flower and made a digital colourful mesh, which you can open in any CAD program or even windows10 can open it in 3D. Find the files on thingiverse here: https://www.thingiverse.com/thing:3843542
