Abstract
Displacement of the spinal cord inside the spinal canal may occur as a result of posture change. Considering the total geometric accuracy of spine SBRT, MRI-defined spinal cord position is sufficiently reproducible and requires no addition to the typical setup-and-intrafraction motion PRV margin if posture is identical throughout the RT process.
