Thank you for the information, and I've tried the software Surf Ice.

I tried to load a head CT dataset, but the software failed to reconstruct the scalp (skin of the head) from this dataset.
Instead, the software showed a weird 3D surface reconstruction (as attached).

I am wondering if the software is intended to perform such tasks as reconstructing the scalp?
If yes, is it possible you could provide further guidance on how I could achieve this?

You are really appreciated!
