Meet the Radiation Medicine Team

Radiation Oncology Physicians

Radiation oncologists are physicians who are responsible for the medically appropriate and technically correct radiation treatment of patients with cancer. All of our radiation oncologists are board-certified in therapeutic radiology by the American Board of Radiology, licensed by the New York State Department of Health, and comply with the American College of Radiology standards of care.

The Medical Physics Team

Our board-certified medical physicists are an important part of our multidisciplinary Radiation Medicine team, designing and maintaining the quality assurance of every individual treatment plan. They ensure that information has been correctly transferred to the machine, that the plan agrees with the physician’s prescription, and that all information is consistent, understandable and well-documented. They also contribute to the development of therapeutic techniques and collaborate with team members to design treatment plans.

The Medical Dosimetry Team

Medical dosimetrists are professionals who design radiation treatment plans specific to each cancer patient’s prescription as determined by the radiation oncologist. This is done with state-of-the-art 3-dimensional graphics and patient imaging collaboration with other radiation oncology professionals.
