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 in a single session. The method facilitates treatment of very small tumors deep within the brain. Patients are immobilized with a rigid head frame that is secured with small, titanium pins.

Mayfield provides Gamma Knife treatment at Jewish–Mercy Health

Mayfield Clinic neurosurgeons based at The Jewish Hospital – Mercy Health are now using Gamma Knife® to treat patients with benign, malignant, and metastatic brain tumors. 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 2,500 published medical papers have underscored the safety and effectiveness of Gamma Knife® radiosurgery. Worldwide, more than 600,000 patients were treated with this method between 1983 and 2010. More than 250,000 of these patients were treated for metastatic brain tumors.

 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.

 Precision Radiotherapy focuses on patient safety, research, and community

Precision Radiotherapy, a partnership of the Mayfield Clinic and UC Health’s Department of Radiation Oncology, provides skilled, compassionate care to 80 patients each day at its West Chester, Ohio, location.

We have more than 20 years of experience in the safe delivery of complex radiation treatments. Our specialists are certified by the American Board of Radiology, and our safety protocols call for daily, weekly, monthly, and annual checks of the accuracy of our equipment. Our team pioneered frameless radiosurgery with the Novalis® system, and we have published 15 academic articles in national, peer-reviewed journals.

Our efforts are also reflected in patient satisfaction surveys, with 97 percent of patients providing high marks for overall satisfaction, quality of care, confidence in our team, and the likelihood that they will recommend Precision Radiotherapy to others.

In addition to providing state-of-the-art clinical care, Precision Radiotherapy Center contributes $300,000 annually to the UC Brain Tumor Center for research and education.


 Creating the Stereotactic Mask

A stereotactic mask is custom-made to fit your face exactly and is used during each radiation treatment session. Thermoplastic mesh is dipped into a warm water bath, making the mesh very flexible. The mesh is placed over your forehead, nose and chin, and gently molded to conform to your face. The mesh dries quickly. Creation of the mask takes about 30 minutes.

Watch a video narrated by Dr. Warnick, who will walk you through the process of creating the mask.

Patients who have undergone radiosurgery both with a head ring and with a mask, clearly preferred the latter method.
