Inserting throats to X-ray image

[dpereponov]

Hello!

Currently, I'm working on the creation of the microfluidic chip using a scan of computer tomography.
The resulting CT image shows only large pores without any connectivity. Using the SNOW algorithm, I found the centers of all the pores. If it's possible, could you tell me which function (or a set of them) will help me add pore throats?

I really appreciate any help you can provide.

So your CT scan did not resolve the throats? I wonder if you could use just a regular 2D microscope image since it's a microfluidic chip? We had a discussion about this with someone else recently. Anyway, assuming that you must proceed with your CT image, the first option that occurs to me is a Delaunay tessellation. If you have points at the centers of each pore, you can use the Delaunay tessellation to connect nearby pores. OpenPNM has a function for converting the results of a Delaunay tessellation into a pore network (tri_to_am). It's not totally straight-forward to go from the the am to a useful pore network, so if you go this route I can help. Perhaps you can start by posting your image here, or sending to me at jgostick at gmail.com?

Thank you, Professor! I have sent you the image by email.
