摘要：
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 1H 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).
