[slicer-users] Comparing difference between two scans

This is not really a Slicer question, but I thought I might get some
pointers towards the right direction.
We would like to compare scans from two different microCT scanners.
These are not medical scanners and are not calibrated to any standard.
We want to measure how much difference there is at the end by using the
standard procedures of the two facilities. For that, we thought of
looking at the trabecular bone structural parameter estimates, and
measure the extend they differ (if they do at all).
But given that we will be scanning identical specimen, I thought there
might be a better measure of overall difference. In theory, these two
datasets should register perfectly and any difference can be attributed
to the difference in scan quality and/or reconstruction parameters. But
I don't know how we can convert this difference in a some kind of metric.
