MRIcro MRIreg registers a MRI scan with scalp locations

http://www.sph.sc.edu/comd/rorden/mrireg.html

It is often useful to coregister a MRI scan with the subject's real head geometry - for example, with Transcranial Magnetic Stimulation, it is useful to have a precise idea of which region of the brain is being stimulated. MRIreg is a free tool that allows you to identify which region of the scalp is near a particular brain region. To use MRIreg you will need:
  1. MRIreg for Windows [free, shift+click here to download version 0.995].
  2. MRIcro for Windows [free from the MRIcro home page].
  3. A MRI scan for the person you want to register.
  4. An Ascension Flock-Of-Birds/MiniBird or Polhemus Fastrak magnetic position tracker.

It is easiest to get good results from coregistration by using MRI scans where you have marked easy-to find landmarks on the individuals face or scalp (e.g. place liquid-vitamin gel-capsules on their facial beauty marks during scanning). You will need to find at least 5 anatomic landmarks.
