Gamma Knife®

Gamma Knife Feature

Princess Alexandra Hospital is the home of Gamma Knife® Centre of Queensland. This is the only Gamma Knife® technology available in the public hospital system in Australia and the first and only service in Queensland.

Our new Gamma Knife® service compliments Princess Alexandra Hospital’s reputation as a Centre of Excellence in cancer care and treatment and will establish our service as a world-class radiosurgery facility.

The Gamma Knife® is a non-invasive alternative to neurosurgery which uses radioactive sources to predominantly treat brain tumours. It delivers treatment called stereotactic radiosurgery which is a highly precise form of radiation. It can be used to treat various brain conditions including malignant or benign tumours. Gamma Knife® enables patient planning and treatment to be done on one day as an outpatient procedure. It is the most accurate way to deliver intra-cranial radiosurgery particularly for treating multiple lesions.

The biggest benefits for patients are that treatment involves less risk of complications, less side effects, and a reduced impact on quality of life.

Princess Alexandra Hospital commenced the Gamma Knife® service in October 2015.

About Gamma Knife®

Gamma Knife® surgery is a well-established method to treat selected targets in the brain; but it is not a knife. Instead, highly focused beams of radiation are directed to the treatment area in the brain.
