A magnetic resonance position and orientation marking system includes fiducial assembly ( 30 ) with at least three fiducial markers ( 31, 32, 33 ) each coupled with at least one magnetic resonance receive coil ( 70, 74, 80, 84 ). At least one of the fiducial markers has at least one of: (i) marker nuclei selectively excitable over <SUP>1</SUP>H fat and water resonance, 5 and (ii) a plurality of magnetic resonance receive coils ( 70, 84 ) coupled therewith. At least two magnetic resonance receive channels ( 40, 42 ) receive magnetic resonance signals from the at least three fiducial markers ( 31, 32, 33 ) responsive to excitation of magnetic resonance in said at least three fiducial markers by a magnetic resonance imaging scanner ( 10 ). |
