To evaluate intrafraction motion during spine SBRT with different immobilization systems and determine whether less rigid systems can offer similar geometric accuracy to near-rigid systems such as the BodyFIX during FFF VMAT treatments.

To design and validate a Monte Carlo electronic portal imaging device (EPID) model to reduce the uncertainty in the calibration of EPIDs for in-vivo dosimetry of external beam treatments by consolidating correction factors into a single direct measurement.
