Gamma Knife vs. TrueBeam STx for Brain Tumors

One of Rush Radiosurgery’s many focus areas is the treatment of brain tumors using TrueBeam STx® technology, an advanced machine that treats tumors with high-dose radiation delivered with sub-millimeter accuracy.

When facing a brain tumor diagnosis, it’s important to understand different treatment options in order to make the best decision for your case. Read below for a treatment comparison of our center’s TrueBeam STx machine and Gamma Knife®, another technology that delivers stereotactic radiosurgery for brain tumors.

  • Treatment areas – While Gamma Knife® treats cancers only located in the head and neck areas, TrueBeam STx is able to treat a variety of cancers in many areas of the body.
  • Comfort – The accuracy of Gamma Knife® is achieved by stabilizing the patient’s head using an invasive metal frame, while brain tumor treatment with TrueBeam STx is completely noninvasive and doesn’t require a fixed metal head frame attached to the skull to stabilize the patient. With TrueBeam STx, patients undergoing treatment simply lie on a treatment table wearing a mesh face mask during their session, as the machine rotates around the patient and automatically adjusts and corrects for any patient movement.
  • Sedation – Because brain tumor treatment with Gamma Knife® uses a metal head frame to secure a patient’s head, local anesthesia is required to eliminate any pain and discomfort during the process. Treatment with TrueBeam STx, however, is painless and does not require any anesthesia or a metal head frame, allowing patients to resume their normal routines immediately following treatment.

Our center treats a variety of cancerous and benign brain tumors using TrueBeam STx technology. For more information about our treatment method contact us.
