A self-calibrating through-time spiral GRAPPA method is presented that uses the same undersampled scan for both the accelerated data and the calibration data. This method can be used to capture at least one heartbeat worth of data at 12 slice positions in less than one minute, in a free-breathing and ungated scan.
