文摘

We propose a method for constructing flexible head-casts to stabilize the head during MEG scanning. Co-registration error is minimized by using MRI images to pre-define fiducial coil locations. Within- and between-session movement is <0.25 and <1 mm respectively. This enables high reproducibility of source level results.
