In fMRI time series temporal SNR is reduced by field
drifts as well as physiological noise such as stemming
from breathing or limb motion. To address this problem
we present the use of a real-time field control system
to compensate for field fluctuations independently of
the employed sequence without the need to alter image
reconstruction or additional pre-processing.
