Electromagnetic transmitter-based prostate gating for dose-escalated SBRT

Evaluates intrafraction motion magnitude and gating frequency using The Raypilot System's EM tracking. Reports the proportion of fractions where gating was triggered and the clinical impact.

Why it matters: The study shows that the Raypilot System can be easily incorporated into routine prostate LINAC-based SBRT workflows. Its use enabled the safe application of a 2 mm CTV-to-PTV margin. The study also shows that without intrafraction motion control, prostate motion would have gone undetected.
