Abstract
⺠New Bayesian method for removing physiological noise from fMRI data. ⺠Cardiac and respiration frequencies from reference signals with the IMM algorithm. ⺠Possible to estimate the frequencies from fMRI data if time-resolution allows. ⺠Separation of fMRI into activation and noise with Kalman filtering and RTS smoothing. ⺠Outperforms the RETROICOR method when physiological signals change much over time.
