Stereotactic Radiosurgey is a very accurate and specialised treatment which we deliver using a Gamma Knife. The Gamma Knife is not a knife in the conventional sense, but uses a focused array of intersecting beams of gamma radiation to treat lesions within the brain. The technique was invented by a Swedish neurosurgeon, Professor Lars Leksell and provides an alternative method of treatment for a number of conditions, for which open neurosurgery may be either not practicable or carry a high risk of complications.
Within the central body of the Gamma Knife there is an array of 192 separate cobalt sources each of which
produces a fine beam of gamma radiation.
The sources are evenly distributed over the surface of the hemispherical source core with the beams directed towards a common focal spot at the centre. (see What Is a Gamma Knife in the Treatment section)
The resultant intensity of radiation at the focus is extremely high whilst only a short distance from the focus it is very low. This enables a high dose of radiation to be delivered to the abnormal tissues whilst sparing the adjacent healthy brain tissue.
