With the technology of 3d scanning, I was wondering if anyone in the NIRS or EEG research community has utilized it for acquiring 3d digitizer data aside from the Polhemus. My lab uses the Polhemus, but it is often prone to funny errors and data that doesn't look great when we use it for localizing channels. Was hoping to find an easier and faster way and if that is even out there.
Hi Andrew,
At the Donders we have considered this for EEG rather than fNIRS. As alternative to the Polhemus, we tried a Fuel3D and as of very recently got ourselves a structure.io scanner. We did not like the Fuel3D for various reasons, but the structure.io appears to work quite well. We just added support for its data format in FieldTrip (see http://www.fieldtriptoolbox.org, it is in the ft_read_headshape function) and will continue working on this to get a good (EEG/MRI/headmodel) coregistration pipeline documented. I hope that our efforts will also be helpful for fNIRS, for which FieldTrip is also useful. If you want to chime in in detail, please do so at http://bit.ly/1SPRkto.
best regards,
Robert
Hi Robert,
Thanks for this information. We'll look into it. Can I ask why you didn't like the Fuel3D?
Thanks,
Andrew
