Freesurfer Brain and SEEG Electrodes in CURRY

Importing Freesurfer pial surface into CURRY gives great visual representation of SEEG electrode locations. In the figure above, the screenshot was taken of a left lateral view of the pial surface model and then copied into PowerPoint where the labels were added.

In CURRY 8 you can import Freesurfer segmentation results such as the pial surface (lh.pial and rh.pial) files. You will need to co-register the Freesurfer files using the T1.mgz image data file.

To import your Freesurfer anatomy files into CURRY follow these steps:

  1. You will need lh.pial, rh.pial & T1mgz.
  2. Add T1.mgz to (Insert Image Data File) to the patient study
  3. Switch to Freesurfer coordinates (Freesurfer, NiftTi (R,A,S)
  4. Go to the Results panel, right-click on Surfaces and load lh.pial, hit OK.
  5. Hit No when asked to Add color intensity.
  6. CURRY will then ask you if you want to load the contents of rh.pial. Hit Yes.
  7. When finished, you should see lh.pial rh.pial in the Results and Objects list. Both left and right hemispheres have been combined.
  8. You now have your Freesurfer brain.
