25 Years of SBRT with CyberKnife

July 7, 2021

“We will present the physician and physicist perspectives of the lessons learnt from 25 years of SBRT including the technical and practice advances, and possible explanations for the 10 times lower complications risk that was observed when averaged over several datasets with Synchrony.”
