To
overcome image artifacts induced by motion the use of navigator signals has
been proposed, combined with either real-time correction of the data
acquisition or motion compensated reconstruction. The quality of the
correction depends critically on the estimated motion derived from the
navigator signal. We present a fast, robust and precise algorithm to evaluate
data from an orbital navigator trajectory and its application to motion
compensated reconstruction.
