Gamma Knife/Stereotactic RadiosurgeryBased at Aurora St. Luke's Medical Center, Aurora Health Care installed the first operational Gamma Knife in Wisconsin in 1999. The Gamma Knife is a state-of-the-art, high technology tool dedicated to performing radiosurgery of brain lesions, AVMs and functional neurological disorders.
Gamma
Knife is typically used to treat primary malignant, metastatic or benign
brain tumors, arteriovenous malformations and debilitating conditions such
as trigeminal neuralgia and functional disorders.

The Gamma
Knife houses 201 radioactive cobalt sources that allow all 201 beams to
converge on a defined brain target with amazing accuracy. This highly
intense radiation dose allows the target to receive the dose with minimal
effect to surrounding tissue. The Gamma Knife offers advantages
to external beam radiation treatments because small and complex shaped
tumors are more easily and more accurately treated.
With Gamma Knife radiosurgery, patients can be treated in an outpatient
setting and do not need invasive, traditional brain surgery. A team of neurosurgeons,
radiation oncologists, radiation therapists and medical physicists work together for the
selection, planning and treating of patients.
