MARKER TRACKING FOR INTERVENTIONAL MAGNETIC RESONANCE |
摘要 |
A fiducial marker assembly (30) is tracked using a magnetic resonance scanner (10). At the tracked position of the fiducial marker assembly, local B0 magnetic field inhomogeneity is measured. A warning is issued if the measured local B0 magnetic field inhomogeneity satisfies a warning criterion. A noise figure of merit of the tracking is also determined, and the warning is also issued if the noise figure of merit satisfies a noise-based warning criterion. |
