Gamma Knife is a device used for intracranial precision radiosurgery. This method provides an alternative to surgical procedures with scalpel use. Traditional surgery within the head area is complex and impossible in many cases due to the number of sensitive organs located therein. Modern medicine allows a precise removal of tumour by means of a device emitting a high dose of radiation onto a designated site. The process is performed under an ongoing monitoring of procedure-monitoring devices.

Gamma Knife is a therapeutic method used by Exira company, a partner of NU-MED Center for Diagnostics and Oncology Therapy in Katowice, one of the four centers of NU-MED Group.
