Recently I had an MRI done on me as part of an MRI scanner operator training session. I decided to hold a face for the T1 scan, which is actually quite difficult because the process takes 5 minutes. Muscles in your face, I believe, aren't supposed to hold the same expression for several minutes in a row, and if you ever try it you'll find your face muscles twitching quite a bit.

I got a copy of my scan and used AFNI and Blender to render the voxel data as I described in an earlier post. I can't decide if the result is creepy or funny looking, haha.
