WEBINAR: Treating Tumors that Move: The Promise and Practice of Real-time MR Image Guidance During Radiation Beam Delivery

Respiratory tumor motion often complicates the delivery of precision radiation treatment. Over the past two decades, radiotherapy researchers and clinicians have pursued several approaches to motion management. However, the approaches lacked continuous, high-quality soft tissue visualization linked to an automated beam-gating technology that would see when a tumor moved out of margin range and halt the delivery of radiation until it returned to a prescribed area (PTV).

With the introduction of magnetic resonance image (MRI) guidance and real-time image guidance during beam delivery, the ability to lessen or eliminate radiation dose to surrounding tissues and organs is achievable. Several studies have demonstrated: (1) the ability to reduce to a minimum the margin expansion necessary to account for motion error while reducing doses to nearby organs at risk, and (2) the ability to obtain duty cycles equal to or greater than those common to conventional gating.

In this webinar, two speakers will share their clinical experience with this MRI-Guided RT technology.

John Ng, M.D.
Assistant Professor and Director of Medical Student Education in Radiation Oncology at Weill Cornell Medicine
[email protected]

John Ng is a Board Certified Radiation Oncologist and Assistant Professor of Radiation Oncology at Weill Cornell Medical College/New York Presbyterian Hospital. Dr. Ng attended Columbia University and then received an M.S. degree in Biophysics from Harvard University. He obtained his M.D. degree from Harvard Medical School, jointly with the Massachusetts Institute of Technology, as part of the Health Sciences and Technology (HST) program. Joining Weill Cornell Medical Center, he serves as attending physician for Breast Oncology and for Gastrointestinal Oncology. His current focus is on exploring emerging radiation technologies such as magnetic resonance imaging (MRI) guided radiation as a way of amplifying the host immune response to cancer cells.
