Intracranial Stereotactic Radiosurgery Concepts and Techniques

Stereotactic radiosurgery was conceptualized to treat functional diseases of the brain. The need for devices capable of molding the radiation dose to the nuances of intracranial lesions and yet preserve brain function became a challenge. Several devices capable of performing radiosurgery of high quality became commercially available, each with advantages and disadvantages. Speed of radiosurgery delivery for cost effectiveness and comfort for the patient are currently-the main developments in the field. Nuances of these devices, procedural steps of radiosurgery, and the team approach of radiosurgery are discussed in this article.
