This educational webinar will highlight situations when sub-millimeter accuracy is critical and will focus on the real‑time motion management and tracking technologies available on the CyberKnife® System, with particular emphasis on the treatment of peripheral, central and ultra‑central lung tumors, spinal lesions, and intracranial targets.
The session will review the clinical and technical challenges associated with treating targets that are either subject to motion or located near critical anatomical structures, where precision is essential. Attendees will gain an overview of CyberKnife tracking methodologies, including respiratory motion compensation, skeletal tracking, and cranial tracking, and how these approaches enable accurate dose delivery without treatment interruption.
Clinical examples and workflow considerations will be used to illustrate how real‑time tracking can support decreased margins, improved confidence in target localization, and safe treatment of complex cases. The webinar will also discuss practical considerations for site selection, tracking method choice, and interdisciplinary coordination across radiation oncologists, medical physicists, and radiation therapists.
Learning Objectives
By the end of this webinar, participants will be able to:
- Describe the principles of real‑time motion management and tracking on the CyberKnife® System for peripheral, central lung, ultra‑central lung, spine, and brain treatments
- Identify various treatments where sub-millimeter precision is needed to support precise dose delivery near critical structures
- Understand how real‑time tracking supports precise dose delivery near critical structures
- Apply tracking method selection considerations into critical clinical workflows in lung, spine, and intracranial radiosurgery/SBRT

Presenter: Kristin J. Redmond, M.D., MPH
Professor, Director of Spinal Oncology Multi-Disciplinary Program, Departments of Radiation Oncology and Neurological Surgery, The Johns Hopkins University
John Hopkins Medicine, Maryland, USA
Dr. Kristin Redmond specializes in the treatment of brain tumors and leads the spinal oncology multi-disciplinary program at the Johns Hopkins University School of Medicine where she is a member of the Miller Coulson Academy for Clinical Excellence. She received her undergraduate degree from Princeton University where she graduated magna cum laude with a focus in neuro-psychology. She attended medical school and obtained a Masters in Public Health in health systems management at Tulane University where she was elected to the Alpha Omega Alpha Honor Medical Society as well as the Gold Humanism in Medicine Honor Society.
Dr. Redmond’s research interest focuses on the development of novel radiation techniques and therapeutic agents to treat brain and spine tumors in order to increase tumor control and overall survival. In addition, she is working to develop innovative approaches to try to limit long term toxicities and minimize neuro-cognitive dysfunction following treatment for tumors of the central nervous system.
