1. A functional magnetic resonance imaging method comprising the steps of:

  • (a) detecting a physiological timing profile;

    (b) measuring cerebral k-space data;

    (c) ordering the measured cerebral k-space data into a unit cycle based on the detected physiological timing profile;

    (d) estimating corresponding physiological effects for individual k-space data points by non-linear least-square fitting of cerebral k-space data;

    (e) removing the estimated physiological effects from the cerebral k-space data by subtraction, providing cerebral k-space data from which the estimated physical effects have been removed; and

    (f) providing an image from said cerebral k-space data from which the estimated physical effects have been removed.
