Dr. George Ding is Associate Professor of the Department of Radiation Oncology at Vanderbilt University. His primary research area is improving accuracy and precision in radiation treatment of cancer through the study of clinical electron and photon beams and accurate dose prediction in radiation treatment planning.
He is an expert in radiation dosimetry and application of Monte Carlo techniques to radiotherapy treatment planning. His earlier work is at the heart of the BEAM code used throughout the world for Monte Carlo simulation of medical accelerators. His work on water-to-air stopping-power ratios provides important dosimetric data for radiotherapy reference dose calibration. This new understanding led to a new reference depth for more accurate electron beam reference dose calibration. Both recent American Association of Physicists in Medicine (AAPM) dosimetry protocol TG-51 and the international dosimetry International Atomic Energy Agency (IAEA) TRS 398 protocols adopted the new reference depth for electron beam calibration.
His research interests include small field dosimetry used in stereotactic radiosurgery, image-guided radiation therapy (IGRT), stereotactic body radiation therapy (SBRT), accurate dose predictions and measurements in inhomogeneous medium especially in lung cancer treatment, radiation dosimetry, implementation of Monte Carlo based treatment planning, dynamic conformal arc techniques of delivering a conformal treatment, and intensity modulated radiation therapy (IMRT).
