What Is Rotating Gamma Technology™?

Beverly Oncology & Imaging is not currently offering Gamma technology, but will be offering a similar therapy soon. Contact Beverly Oncology & Imaging for more details.

Southern California Noninvasive Brain Surgery

Beverly Oncology & Imaging uses the Rotating Gamma System® (RGS) Vertex360™ to perform noninvasive brain surgery safely and effectively. This radiosurgery device has radioactive sources that rotate and circle the head during treatment, accurately targeting tumors and lesions while preserving the surrounding, healthy tissue. These sources resemble small discs and emit radiation that a patient will not feel. The RGS Vertex360's unique rotating sources and helmet-free design speed up patient treatment time and allow surgeons to more-accurately target tumors and treat brain disorders.

How does Rotating Gamma Technology™ work?

The Rotating Gamma System features two sets of rotating bodies. The outer body houses the radioactive sources with a combined initial source strength of 6,000 Ci (curie, a unit of radioactivity measurement). The inner body houses collimators of various sizes. Collimators produce a beam of radiation, and varying collimator size allows for radiation beams of different strength to be produced.

Built-in secondary collimators are distributed inside the source carrier. When the RGS Vertex360 is not treating a patient, all sources are aligned with a dead-locking position on the secondary collimators, essentially blocking all radiation. At the beginning of treatment, the sources and primary collimators are aligned automatically with the secondary collimators of a user-selected diameter. During the treatment, the source carrier, the primary collimator, and the secondary collimator rotate as one unit. This is done while the patient rests comfortably.

By rotating the source body, primary collimators, and secondary collimators together, a smaller number of radiation sources can be utilized. As the beams converge, the radiation dose to healthy tissue surrounding the target can be reduced as the dose to the normal tissue is spread over a greater volume.

Achieving a New Standard of Care in Radiosurgery

Rotating Gamma Technology™ represents one of the highest advancements in medical science and technological innovation. By allowing surgeons to localize, target, and precisely treat tumors and abnormalities in the brain, this treatment has proven to be a safe and effective alternative to invasive surgical procedures. It also provides hope to people for whom invasive surgery is not an option, particularly when tumors are not easily accessible.
