Gamma Knife Stereotactic Radiosurgery

Gamma Knife Stereotactic Radiosurgery | Pediatric Radiation Oncology | Atlanta Piedmont Hospital installed the fourth Gamma knife unit in North America over 20 years ago and has had
continuous experience in the use of this device ever since.

Gamma Knife Surgery is a minimally invasive procedure that treats tumors and vascular abnormalities within the brain with intersecting beams of radiation therapy, eliminating the need for traditional open neurosurgery. This procedure is commonly used to treat brain tumors, arteriovenous malformations, acoustic neuromas/schwannomas, trigeminal neuralgia and other abnormalities within the brain.

During this procedure, your doctor will use imaging guidance to pinpoint the exact location of the tumor or lesion for precise delivery of the radiation energy. The 201 individual beams are too weak to harm the brain tissue that they pass through, and are only effective at the specific location where all of the beams meet. This procedure requires no incisions and dramatically reduces the risks of infection, bleeding and anesthesia problems commonly associated with traditional neurosurgery. 

The gamma knife radiosurgery procedure is performed in one day on an outpatient basis, with patients usually able to return home the same day. Some patients may experience headaches or nausea after treatment, but these side effects are rare. The results of this procedure may take weeks or months before becoming apparent, but most patients experience effective results that prevent their tumor or lesion from growing any larger.

Pediatric Radiation Oncology

Radiation therapy can be used to treat nearly any type of cancer in any part of the body, and is often most effective in treating solid tumors of the organs, as well as cancer of the bones, brain and blood. Patients of all ages can benefit from radiation therapy, including children from infant to adolescent. Peachtree Radiation Oncology is proud of our record of over 15 years of continuous experience treating the most complex pediatric malignancies.

  • External Beam Radiation Therapy (EBT) – this procedure involves precise delivery of radiation energy to the tumor over the course of several short treatment sessions. This painless procedure minimizes the damage to surrounding healthy tissue. Often, Intensity-Modulated Radiation Therapy (IMRT) is utilized to further reduce dose to surrounding normal structures.

Radiation therapy can be used to slow tumor growth, prevent cancer from spreading or recurring, or to relieve symptoms caused by the disease. This treatment is sometimes administered before surgery so that less tissue needs to be removed, or after surgery to destroy any cancerous cells that remain. Certain cancers can be treated with radiation alone.

There are several different types of radiation therapy that can be used to treat cancer. The best type for your child depends on his or her individual condition, but may include:

  • 3-Dimensional Conformal Radiotherapy (3D-CRT) – CT or MRI scans are performed to produce detailed, three-dimensional images of the area being targeted to reduce the risk of irradiating healthy tissue around the tumor.
  • Gamma Knife Stereotactic Radiosurgery – this is a special treatment used for tumors and lesions in the brain and involves a machine that targets cancer cells to deliver radiation energy. The patient's head is placed in a helmet-shaped device to keep the head in position for precise treatment.

Our doctors strive to perform treatment that is both comfortable and effective for your child's individual condition.


Our physicians are highly experienced in treating all malignant and benign conditions for which radiation therapy is indicated. If you should have a question about whether or not a particular treatment is offered in our office, please feel free to contact our office by telephone.
