Those were high resolution slices of CT scan and nice visualization as well. One can only hope human CT scans could achieve this level of preciseness without increasing the radiation dose.
It looks like a pretty standard scan to me and the article says the protocol used is an extremity protocol.
I work in radiology and various non-human things go though the scanner from time to time - fruit, pets, fossils, broken equipment that needs internal visualisation (sort of like the patients).
I’ve just checked our PACS. The extremity protocols are at .6mm, face at .75mm and spine is 1mm.
It was .6mm 10 years ago when I ran them at other sites, so I don’t think this is anything pioneering.
You possibly do the same, but we generally reconstruct thicker. 1mm acquisitions reconstructed in another plane at 1mm look a bit gross as the acquisition needs to be thinner than the recon.
The dose is not high on modern equipment.
> It was scanned on a GE Revolution CT machine. The scan was performed using technique optimized for human extremities, and employed very thin slice thickness of 600 microns.
