RE: error localizing electrodes
Hi Hanna,
I have been using the electrode editor for a while and it works pretty good. Eventually I got offset but it is due I was co registering the CT with a pre-op MR. If you co-register the CT with a post-op MR the result is very accurate.
In your case, did you use a pre or post- op MR? Did you double check the coregistered MR? Once I use the MR co-registered, the electrodes fall in position. Eventually I do a manual adjustment. But in general it works pretty well.
Based on your image it looks the MR space is different from the CT space where the electrode objects were generated.
Cheers
Magno
