  • 3D dataset comparison

    Dear Collegues,
    we are developing some new methods to generate accurate CT-scan
    reconstruction starting from a small number of slices. The major problem
    we are facing is the following:

    as a test of our algorithms, we have a cadaveric specimen scanned at every
    mm. We subsample this dataset using our method and we generate another 3D
    dataset by interpolation.
    Question: How can we compare to three-D dataset possibly obtaining a
    sinthetic parameter of the overall error?

    I understand that this question could be equally placed in some newsgroup;
    unfortunately, I've not news access right now. So, if somebody would like
    to forward the question to other groups I'd be glad.

    Thanks a lot in Advance.
