Once and once only.

From November 2009 onwards, the Gamma Knife Krefeld Centre was the first high-precision radiotherapy centre in Germany to use one of the most modern radiosurgical devices in the form of the Perfexion Gamma Knife in the treatment of tumours and blood vessel malformations within the skull.

Since early 2011, we have also used the Elekta Axesse device - one of the most precise, high-performance linear accelerators in the world.
