Stereotactic Radiosurgery

Woman Receiving Radiation Therapy Treatments for Head & Neck Cancer with Head Cast

The Advanced Neuroscience Network is proud to offer its patients multiple forms of Stereotactic Radiosurgery (SRS). This type of procedure utilizes many precisely focused radiation beams to treat tumors and other symptoms in the brain, neck, and any other parts of the body that may need treatment. This type of procedure utilizes 3-D imaging to target high doses of radiation to the affected area without harming surrounding healthy tissue.

SRS of the brain and spine are typically completed in a single session, however other parts of the body such as lung, liver, adrenal and other soft tissue tumors may require more sessions to perform the procedure.

Types of stereotactic radiosurgery

  • Linear accelerator (LINAC) machines use X-rays (photons) to treat cancerous and noncancerous abnormalities in the brain and other parts of the body. The Advanced Neuroscience Network has a linear accelerator available to its patients for treatment called the Cyber Knife. This machine can perform SRS in a single session or over three to five sessions for larger tumors.
  • Gamma Knife utilizes small beams of gamma rays to target and treat cancerous and noncancerous brain abnormalities. While the Gamma Knife is not as common as the Cyber Knife, it is available as an alternative treatment option to patients.
  • Proton beam (charged particle radiosurgery) is the newest type of stereotactic radiosurgery and will be available for use within The Advanced Neuroscience Network by the end of 2019 upon completed construction. It will have the capability to treat brain cancers in a single session using stereotactic radiosurgery or use fractionated stereotactic radiotherapy to treat body tumors.

The ability to offer our patients a multitude of treatment options is part of our vision of providing Neurological care from a network approach.

How it works

All types of stereotactic radiosurgery and radiotherapy work in a similar manner. The specialized equipment concentrates several beams on to a tumor or other target. Each beam causes very minimal damage to the tissue it passes through, however it is where the beams intersect at the tumor site that they deliver a high dose of radiation. This causes the tumors to shrink and blood vessels to close off over time following treatment, robbing the tumor of its blood supply.
