Real-Time Motion Tracking and Correction During Tomotherapy for Prostate Cancer: Impact of Fiducial Migration

CONCLUSION: The fiducial-based real-time prostate motion tracking during tomotherapy is advantageous, even in the presence of the measurable IFMs. Our results indicate that, to reduce/eliminate the effect of the fiducial migration on motion tracking stability and accuracy, the fiducial positions on the daily MVCT, instead of the planning CT in the current setting, should be used as the baseline.AUTHOR DISCLOSURE: G.
