I am working with X-ray CT Skyscan 1172 and its accompanied software CT-An. Are you experienced with this device? Can we share some analysing techniques, especially in diffusion mapping and porosity analysis.
We work with CT scan to reconstruct analogue models. We use gOcad implementing the DICOM images as seismic sections, but this is lot of work. We tried to use Mimmics medical software but did not work accurately in our models.
Maybe this Skyscan 1172 software could be useful for our model. In your experience, what do you think?

This is an example of the digital model (Marzal gOcad) and the real simulation (Marzal)
Dear Emilio,
What is the size of your sample? The highest resolution of this Skyscan 1172 device is 800 nm, and in our institute we have been used it to take 3D images and reconstruct some micro samples such as micro-circuit, film, or ceramic moro-specimen. This device is accompanied with some analysis softwares, such as Dataviewer, CT-Vox, which enable user to fully reconstruct their sample at 1um resolution. In my opinion, I think they can work with your model.
I will come back soon with an example of reconstructing image obtained by this device.
I attach here a reconstructing 3D image of my sample, comprised of two parts: ceramic and metal. Using the software, we can control the opacity to view the internal structure of samples or investigate it layer by layer.
Best regards
A number of analysis techniques using CT-an (and the SkyScan 1172) have been outlined in a number of application notes from Bruker MicroCT (formerly SkyScan N.A.).
A few of the notes are openly available on the Web. I am including the URLs below..
1) Morphometric parameters measured by Skyscan CT-AN

2) Structural parameters measured by the Skyscan CT-analyser software….

3) Advanced Porosity Analysis

Additional porosity measurements can be made by using ImageJ. Christopher Liner has a nice little video showing this sort of measurement in rock section at http://seismosblog.blogspot.com/2013/07/thin-section-porosity-estimation-using.html . Also the bonej plugin (http://bonej.org) has a nice particle analysis section that can be used to track porosity in 3D.
Nicolas,
You can contact the company at http://www.skyscan.be/ and ask where the nearest university that they have a scanner installed. Generally, the SkyScan company is quite helpful in finding resources for new users.
Sincerely,
Doug Morris
Malaysian Nuclear Agency owned one table top X-ray Micro CT SkyScan 1172 sponsored by International Atomic Energy Agency (IAEA). Looking forward for scanning request and research collaboration.
