Three technologies for brain & spine
Mayfield Clinic neurosurgeons use three different radiation technologies in the treatment of patients with primary or metastatic brain tumors, spinal tumors, and other neurological abnormalities, such as trigeminal neuralgia, arteriovenous malformations, cavernous angiomas, and chronic pain. Whether your radiation treatments are delivered by Novalis®, TrueBeam™ or Gamma Knife®, your experienced Mayfield physician will provide you with world-class care.
Novalis® Shaped Beam™ Surgery system uses image guidance and precisely targeted x-ray beams to safely treat tumors and other abnormalities of the brain and spine. Patients are immobilized in a fabricated mask that is custom fit to the patient's head.
TrueBeam™ enables precise, shaped-beam radiosurgery and radiotherapy of almost any tumor or abnormality. Using electron beam radiotherapy, TrueBeam™ can also treat tumors that are close to the surface of the body, including skin cancers. Patients are immobilized with a custom-made mask or body mold.
Gamma Knife® uses precise, high-intensity gamma rays to target lesions. When treatment involves a single tumor or lesion, or only a few tumors, a single dose of radiation is given in a single session. When treatment involves many tumors or a large tumor, radiation is given in five sessions. During single-session treatment, patients are immobilized with a rigid head frame that is secured with small, titanium pins. During five-session treatments, patients are immobilized with a custom-fit facemask.
Mayfield provides Gamma Knife treatment at Jewish–Mercy Health
Mayfield neurosurgeons based at The Jewish Hospital – Mercy Health use Gamma Knife® to treat patients with benign, malignant, and metastatic brain tumors; trigeminal neuralgia; arteriovenous malformation (AVM); cavernoma; and essential tremor (in rare situations). No incision is made, and most patients are able to go home the same day. More than 30 years of clinical studies documented in more than 2,800 published medical papers have underscored the safety and effectiveness of Gamma Knife radiosurgery. Worldwide, more than 1 million patients have been treated with this method during the last 40 years.

One might say it was the storm before the calm. By the time Jordin had driven herself to Mercy Health – West Hospital, her head ached so badly that she could barely open her eyes. No, she did not have a history of headaches, she told the emergency room physician. No, the headaches during the last few weeks were not like anything she had ever experienced before.
Multiple technologies, one high level of expertise
Although the technologies behind Novalis®, TrueBeam™, and Gamma Knife® differ, the objective of these "incisionless surgeries" is the same: to destroy a tumor or abnormality by bombarding it with precisely targeted beams of radiation while preserving healthy tissue.
Radiosurgery uses high doses of radiation in 1, 3 or 5 treatments, while radiotherapy uses lower doses of radiation given in as many as 30 to 35 treatments. Radiation works by damaging the DNA inside cells and making them unable to divide and reproduce, therefore causing them to die.
In both radiosurgery and radiotherapy, specialists use some of the same navigation tools of surgery, which allow the precise location of the lesion, or tumor. But instead of being removed with a knife, tumors are ablated with a machine: either a linear accelerator that delivers X-ray or electron beams or a Gamma Knife that delivers high-intensity gamma rays from a cobalt source.
