Gamma Knife at Karolinska

Our specialized teams offer treatment for brain tumor and other diagnosis, with the Gamma Knife, which, as such, originates from Karolinska. Karolinska University Hospital provide world-class neurosurgery and hospital care within the entire neurosurgical field. We have a long tradition of neurosurgery and also of treatment with the Gamma Knife.

Gamma knife surgery is a minimally invasive treatment for neurological diseases. The current model focuses 192 radioactive beams on a target area in the brain.

The target can be tumour tissue, a vascular malformation or an area exposed to pain.

The ultra-modern Gamma Knife at the Karolinska University Hospital is a radiosurgery device with precise technology that automatically shapes and moves the beams to best conform to the target. The shape and dose of the radiation is optimized to focus on the target, sparing the surrounding healthy tissue.

The radiation sources are shielded by a 20-ton heavy radiation protection so that you as a patient and the health care-professionals are spared unnecessary radiation.

The treatment is done with high precision and Gamma Knife surgery is an effective and safe treatment.
