The Advanced ROS Therapy Team

Radiation Oncology is a medical specialty in which many highly trained specialists work together to make sure you receive the best treatment and care. You may or may not meet everyone involved in your treatment, some may be working behind the scenes, but it’s helpful to understand the crucial role that each team member plays in your therapy and the nature of their skills and training.

Radiation Oncologists

Two radiation oncologists, Dr. James K. Gerstley and Dr. Margaret J. Torrey, lead and supervise the Advanced ROS therapy team. Radiation oncologists are physicians who have received extensive training in cancer medicine and the safe use of radiation to treat disease. They make the decisions about the most effective way to treat you with radiation, monitor your progress and work closely with your other cancer doctors to provide you with the best possible treatment for your unique situation.

A radiation oncologist has completed at least four years of college, four years of medical school, one year of general medical training, then four years of residency or specialty training in radiation oncology. Advanced ROS radiation oncologists are board-certified by the American Board of Radiology and combined have over 30 years of radiation oncology experience.

Radiation Oncology Nurses

Radiation Oncology Nurses are licensed practical nurses or licensed registered nurses who have special training in the needs of cancer patients. From your initial consultation to your follow-up visits, the nurses are always available to answer your questions, help you manage symptoms and address any concerns you may have. They are a good source of information and are in frequent communication with the physician on your behalf.

Radiation Therapists

Radiation therapists deliver your daily treatment and makes sure that the radiation you receive is given exactly as the doctor prescribed it. They also keep your daily records and check the treatment machines to make sure they are working properly. Your therapist will position you correctly, explain to you exactly what is going to happen and then deliver your treatment. You will get to know your therapist well since you will be seeing each other every day of your treatment. Radiation therapists are specially trained in their field, licensed by the New York State Department of Health and certified by the American Registry of Radiologic Technologists.

Medical Dosimetrists

Dosimetrists have specialized knowledge and training in the clinical characteristics of radiation treatment machines and equipment. Working with the radiation oncologist and the medical physicist, dosimetrists work out the specifics of how to deliver the radiation dose prescribed by the radiation oncologist. They analyze diagnostic imaging scans and perform the computations needed to determine the best plan for each patient. Once a plan is approved, the dosimetrist works with the radiation therapist to implement the plan in preparation for your treatment. Dosimetrists are certified by the Medical Dosimetrist Certification Board.

Medical Radiation Physicists

While radiation has been used to treat disease for more than 100 years, the sophistication and accuracy of today’s technology greatly increases its effectiveness. Medical radiation physicists are scientists who measure and determine the proper dosage of radiation according to the doctor’s prescription. They continually monitor the accuracy of the equipment to ensure that the precise amount of radiation is being produced and delivered to the target area. Our medical physicist manages the complex technical planning of your treatment with the assistance of the dosimetrist. He also oversees our radiation safety program, guaranteeing the protection of patients, staff and the public. Qualified medical physicists have a Doctorate or Masters degree, specialty postgraduate training and are board-certified by the American Board of Radiology or the American Board of Medical Physics.
