given the slow temporal resolution of fMRI
because it depends on blood flow it has a refresh rate of around 10 seconds, so the idea of being able to extract live spontaneous visual imagery its pretty unlikely at the moment. Still pretty impressive though.

The analysis is done post hoc
but is still pretty cool.
