The MEG scanner has a helmet into which a participant puts their head. This helmet is at the bottom of storage dewar, which is full of liquid helium. The storage dewar is mounted onto a gantry, (see Figure 1.1).

When a participant is scanned, the gantry can be moved so as to position the MEG scanner over the participant. The chair on which the particpant sits is then raised up so that the particpants head rests inside the helmet of the scanner (see Figure 1.2 and Figure 1.3)
