Do you mean a phantom with the uniform grid of beads? I don't think that we had anything that would process that. We mainly just visualized it before and after gradient unwarping.

Hi Bruce:

This is an ADNI (Alzheimer's Disease Neuroimaging Initiative) Phantom principally used for structural T1s. The scans have been acquired over 5 sites all over the US on different 3T scanners (Siemens. Philips, GE etc). Basically we are trying to morphometrically evaluate Phantom data to look for inconsistencies between scanners.

thanks,

Alan

    Hi Bruce, Nick, Doug and others:

    I have Phantom data from around 900 scans collected across 5
    sites in the
    US. Does FS have a way of processing Phantom data.

    Thanks much,
