An efficient multistage algorithm for full calibration of the hemodynamic model from BOLD signal responses

We propose a computational strategy that falls into the category of prediction/correction iterative‐type approaches, for calibrating the hemodynamic model. The proposed method is used to estimate consecutively the values of the two sets of model parameters. Numerical results corresponding to both synthetic and real functional magnetic resonance imaging measurements for a single stimulus as well as for multiple stimuli are reported to highlight the capability of this computational methodology to fully calibrate the considered hemodynamic model.
