This study attempts to use video recording as a tool for
physiology monitoring in an MRI scanner. During a
cardiac cycle, facial skin blood perfusion changes alter
optical path of ambient light emitted to the subjects
face. Using a conventional digital camera to capture the
changes of the reflected light and using ICA analysis to
remove other sources in light, we identify that this
method is feasible in a low-light MRI bore. This method
is an optic-based technique which avoids the problem
associated with switching gradient system.
