COLUMBIA, Tenn.— The Maury Regional Cancer Center has added new technology to enhance the precision of radiation therapy for cancer patients, according to radiation oncologist Michael Sattasiri, M.D.

“The rate at which new technology becomes available for the treatment of cancer is promising. The addition of this new imaging system will provide us with even greater accuracy in the delivery of radiation therapy,” said Dr. Sattasiri.

The Varian® On-Board Imager® (OBI) makes dynamic targeting image-guided radiation (IGRT) more efficient and convenient. The system delivers improved tumor targeting using high resolution, low dose digital imaging in the treatment room. OBI provides the tools to manage changes in position caused by day-to-day set-up conditions as well as changes in position during a patient’s treatment session because of normal respiratory and organ motion. This enables physicians and staff to confidently manage patients and target movement—both before and during treatments.

Joel Kochanski, M.D., a radiation oncologist in the cancer center adds, “The use of this new imaging can result in better image quality than traditional megavoltage imaging. By having the best possible image information, we are able to make timely decisions and obtain exact alignment, which is critical when delivering high doses of radiation.”

The Maury Regional Cancer Center will begin using this new technology at the end of the month. OBI is the latest tool added for radiation treatment of cancer and complements intensity modulated radiation therapy and brachytherapy. In addition, the Maury Regional Cancer Center was the first in the state to utilize the dose verification system for the treatment of breast cancer and is accredited by the Commission on Cancer of the American College of Surgeons.
