Donald B. Fuller M.D. is a board certified radiation oncologist who joined Radiation Medical Group in 1988 and is currently one of their managing partners. Dr. Fuller recently published a prostate CyberKnife radiation dose sculpting method known as “Virtual HDR”. This method is now the subject of a large multi-institutional clinical trial. Although Dr. Fuller performs a wide variety of radiation oncology treatment methods for a full range of malignancies, he primarily specializes in the development and application of innovative radiation methods for prostate cancer. His current area of greatest interest is the application of CyberKnife radiosurgery as a method to optimize hypofractionated prostate radiation treatment.
