Stereotactic Radiosurgery

Stereotactic radiosurgery (SRS) is used to treat many types of lesions in the brain, including:

  • Brain tumors
  • Meningiomas
  • Vestibular schwannomas
  • Trigeminal neuralgia
  • arteriovenous malformations (AVM)

A head frame is placed to provide a reference system for treatment planning and to ensure no movement during treatment. High doses of radiation are given to a small area in your brain using multiple arcs of radiation. In most cases it is done in one treatment. The radiation can be intensely delivered to the abnormal area while the normal brain tissue around it receives only a small dose of radiation. The UW Carbone Cancer Center has an active program in SRS and was one of the pioneering institutions in its development using linac-based delivery.
