This webinar will share the results of end-to-end dose measurements for spine stereotactic radiosurgery quality assurance test in both MR-Linac and a conventional linac. Treatment plans were generated for lumbar and thoracic spines. Target and spinal cord doses were measured directly with two ion chambers inserted into the RTsafe Spine phantom. The RTsafe anthropomorphic Spine phantom was used to examine the feasibility of spine SBRT with the MRL.

Eun Young Han is an associate professor of radiation oncology at the University of Texas MD Anderson Cancer Center at Houston, USA. She works as a clinical medical physicist. She earned her PhD at the University of Florida focusing on Monte Carlo-based internal dosimetry using pediatric and adult anthropometric phantoms. Today, her clinical and research interests are in the areas of end-to-end test and dosimetric comparison of brain stereotactic radiosurgery using Gamma Knife ICON and spine SBRT using MR-guided Linac.

Jinzhong Yang is an assistant professor of radiation physics at the University of Texas MD Anderson Cancer Center, USA. He is the physics lead of the MR-Linac programme at MD Anderson. He earned his PhD in electrical engineering from Lehigh University in 2006. Dr Yang has more than 12 years of research experience in medical image registration and image segmentation, with a focus on translating novel imaging computing technologies into clinical radiation oncology practice. His current research interest focuses on MR-guided online adaptive radiotherapy.
