We present a new approach for tracking object motion
during MRI examinations. The approach is based on the
used of spatially encoded coil signatures or
fingerprints. Using this approach, a motion dictionary
can be generated and the corresponding information used
to assign readout signals to distinct motion states that
have been previously identified during a motion-learning
scan. Our results demonstrate that this approach is
effective and can be easily incorporated into most
high-duty cycle imaging sequences used for body MRI.
