More Info On

Radiation therapy, or radiotherapy, uses ionizing radiation to treat malignant cancer cells and shrink tumors. It is often combined with other treatments, such as surgery, hormone therapy and chemotherapy.

Radiation Oncology in Annapolis, Md.

The Radiation Oncology program at the DeCesaris Cancer Institute, accredited for Radiation Oncology by the American College of Radiology, provides a variety of therapies for cancer care. Our team, including radiation oncologists, dosimetrists, radiation therapists and specially trained nurses, treats a variety of cancers with the most focused and accurate technologies available.

Radiation Cancer Treatments

Our treatments, guided by physicians whose specialties span the disciplines of radiation oncology, physics and radiology, identify and “map” the location of tumors with extraordinary precision. Other radiation treatments and planning guides include:

Radiation for Non-Cancerous Treatments

Understanding IMRT

Intensity Modulated Radiation Therapy (IMRT) spares surrounding healthy tissue by delivering extremely precise beams of radiation. Treatment plans are developed using 3-D computed tomography (CT) images combined with computerized dose calculations so the radiation beams conform to the shape of the tumor. This method also allows our team to focus the most intense doses of radiation to the areas where they are most effective.

Understanding IGRT

Image Guided Radiation Therapy (IGRT) utilizes implantable gold markers to make treatments for prostate, head, and neck cancer more effective. These Acculoc gold implants, called fiducials, allow the radiation team to “track” tumors, which may shift slightly due to organ motion, fluids and gasses within the body. IGRT allows our oncologists to maintain tumor margins with confidence, making sure doses are directed with pinpoint accuracy.

We also offer protocol enrollment on national trials for high-risk and postoperative patients who are candidates for radiation therapy through the Radiation Therapy Oncology Group (RTOG).

Novalis: Revolutionary Radiosurgery

Novalis is a highly precise method of radiosurgery that exactly mirrors tumors, thereby protecting healthy tissue from unnecessary irradiation. Learn more about Novalis at AAMC.
