Once again, I suspect this community could be of help in an unexpected capacity.
I have had to recover some medical images from a hard drive (and when I say "I", I mean the idiot who deleted them without backing them up). The idiot/genius who has finally accomplished this is giving them to me in *.nif format. I googled that and found it was a format from Morrowind??! Also that it was an OS2 file format awhile back. Also that it was an old format used for images by Navy hardware. Given that the images were produced by a 15yr old fluoroscope, could anyone here hazard a guess as to which type of nif files these are, and how to view them?
