Radiation oncology is a specialized area of cancer medicine that uses radiation therapy. Radiation therapy is one of the most common treatments for cancer. It is used in more than half of all cancer cases. In radiation therapy, we use high-energy rays to destroy cancer cells in your body. The radiation can be delivered using:
- An external beam from a special machine called a linear accelerator
- Radiotherapeutic devices, implants, or medications that emit radiation from inside your body
History of innovation
1896 Dartmouth performs first diagnostic radiograph (X-ray) in the U.S.
1956 First coined the term Artificial Intelligence (AI) at Dartmouth
2001 First hyperbaric oxygen program within a New England radiation oncology department
2004 First worldwide use of Pd-103 coils: an internally implanted radiation treatment for prostate cancer
2004 Therasphere: 1 of 24 centers in U.S. – microbeads for the treatment of liver cancer
2016 Invention of Cherenkov imaging cameras that allow a visual mapping of the skin surface radiation left by the beam
2017 Space OAR Hydrogel treatment: First center in northern New England. SpaceOAR Hydrogel lessens the impact of radiation therapy on organs close to the prostate.
2021 FLASH XRT: First to use with modified linear accelerator delivery. Using ultra-high dose rates compared to conventional radiation may reduce damage to normal tissue.
We continue to lead the way in research and technology. From the first U.S. use of a diagnostic radiograph (early X-ray) that happened at Dartmouth in 1896, our commitment has always been to innovation that helps us to provide you with the best and most advanced treatments in your journey with cancer.
We use the most advanced computer planning, imaging, and treatment delivery systems to tailor your treatment. This improves outcomes and reduces side effects. Your well-being is of paramount importance to us.
We treat around 1,000 new patients with cancer each year. We provide many different types of treatment options so that we can tailor your care to what you need.
