Stereotactic Radiosurgery

Stereotactic radiosurgery is a minimally-invasive alternative to conventional surgery or radiation therapy. It delivers beams of low-dose radiation from many different angles simultaneously. As these low-dose beams travel through the body, they do not harm normal, healthy tissue. However, the beams converge at the site of the tumor or lesion, where they add up to a powerful dose that can destroy unwanted cells, such as cancer cells.

This treatment is especially helpful for treating disease in places where regular surgery or radiation therapy would harm essential tissue, for example, near the brain, spinal cord or vital organs. In fact, it often makes it possible for doctors to treat conditions that would otherwise be inoperable.

Stereotactic radiosurgery is faster and more precise than whole-body radiation. MidMichigan Health is the only provider in the region that has the most state-of-the art stereotactic radiosurgery devices for both the body and the brain, including:

BodyArray
Gamma Knife Perfexion

Stereotactic radiosurgery dramatically reduces treatment time for radiation therapy on tumors anywhere in the body, and can offer hope for otherwise inoperable tumors. Radiation oncologist Rajnikant Mehta, M.D., describes an optically-guided radiosurgery system called BodyArray that enables high doses of radiation to reach tumors and lesions while sparing healthy tissue and surrounding organs.
