Nice video. What is the headpiece made of? What sort of printer do you
use?
Another interesting concern is whether, if the subject's head is
tightly coupled to the dewar, subject motion can cause unacceptable
shaking and noise inside the sensors. What is your experience with that?
We have experimented with 3d-printing single-piece holders for the head
coils, worn like glasses, which can easily be taped to the subjects,
mostly for repeatability purposes. They are much lighter and don't take
up as much room as a full headpiece. Then we still use towels to keep
them still. :-)
