Radiation Oncology
A patient's individualized cancer treatment plan may include radiation therapy. In this treatment, high-energy x-rays, electrons, or other sources of radiation are used to destroy cancer cells.
Our state-of-the-art equipment includes a CT "Simulator" which creates a three-dimensional image of the exact location of the cancer being treated. ADAC computer software gives the physician an accurate description of how and where the radiation is to be delivered. And two Clinac 21 EX high-energy linear accelerators administer radiation therapy externally.
St. Mary's offers two specialized forms of external beam radiation therapy:
- Intensity Modulated Radiation Therapy (IMRT) helps design and deliver the optimal dose and beam arrangement to precisely treat a tumor of complex shape or location with minimal radiation to surrounding tissue.
- Stereotactic Radiosurgery (SRS) uses three-dimensional images and precise patient positioning to direct a large dose of radiation to a small area.
Some cancers can be treated internally. Brachytherapy is the process of placing seeds or pellets in or near the tumor to slowly release radiation. Brachytherapy performed at St. Mary's Regional Cancer Center includes gynecological implants, prostate implants, strontium and samarium therapy, I 131 therapy, and intravascular brachytherapy.
Specialized Staff
Supporting our three radiation oncologists, radiation therapy nurses answer patients' questions about their treatment sessions, side effects, nutrition, and daily activities. They work closely with radiation therapists who administer the radiation treatments. St. Mary's physicians and physicist develop individualized, precise treatment plans with the assistance of our dosimetrists.
