ABSTRACT

Radiosurgery is the delivery of high radiation doses to a small, well-defined intracraneal target, localized by means of a stereotactic system and delivered trough multiple, narrow concentric radiation beams. Because of its nature, radiosurgery demands a very high level of quality control, independently of the system used. The technique was first developed and applied by Lars Leksell, neurosurgeon from Sweden, in 1951. Since then, several systems have been developed under the same principle but with different radiation sources. More used systems nowadays include the Gamma Knife and the modified linear accelerator. In the present paper, every system is briefly explained and general quality control parameters for radiosurgery are described besides the specific parameters for the two most used systems.
