What is a Gamma Knife?

A gamma knife is an irradiation device with 201 sources of radiation which are all focused on one point. It is comparable to a burning glass as an almost spherical field of radiation appears at the hub, which has a therapeutic effect.

This type of ray concentration allows the irradiation of tumour tissue without harming the surrounding tissue. The total dose of radiation needed to destroy a tumour can be given at a single sitting. Gamma knife therapy is a safe and efficient form of therapy based on over 30 years of clinical experience, and is being constantly developed and improved.
