Measurement of cardiac pulsatile map in the brain without monitoring an external cardiac signal.

In order to obtain cardiac waveforms in the brain for studies with incomplete measurement by pulse-oximeter, we developed a technique to map cardiac pulsation directly from fMRI data itself. We compared the cardiac-phase from our method with that from pulse-oximeter and found they are highly correlated (r > 0.8).
