Template MEG dewar shapes

To help position the subject in the MEG dewar (i.e. the helmet), you can use ft_realtime_headlocalizer in combination with the FieldTrip realtime interface. Template dewar outlines are available for the CTF and the Elekta system and will be loaded automatically. The head localizer allows you to visualize the following geometries:

  • head localizer coils
  • realistic head shape, recorded with Polhemus or Structure Sensor
  • schematic outline of the head as a sphere
  • MEG sensor positions
  • dewar outline

You can find the template MEG dewar shapes included in FieldTrip here.
