Definition of Stereotactic Radiosurgery (SRS)<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Stereotactic Radiosurgery<\/strong> (SRS)<\/strong> is a special form of ionizing radiation therapy characterized by maximum accuracy (<1mm), delivering a large dose of radiation to a strictly defined target, in a single session.<\/p>\n\n\n\n

In special cases (i.e big size of the target or its proximity to a nerve or sensitive structure) SRS can be performed in 3 or 5 sessions (fractionated Stereotactic Radiosurgery) or in one session which is then repeated after several months or years. (staged Stereotactic Radiosurgery).<\/p>\n\n\n\n

A type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. It is used to treat brain tumors and other brain disorders that cannot be treated by regular surgery. It is also being studied in the treatment of other types of cancer.<\/p>\n\n\n\n

Stereotactic radiosurgery (SRS) is a distinct discipline that utilizes externally generated ionizing radiation in certain cases to inactivate or eradicate a defined target(s) in the head or spine without the need to make an incision. The target is defined by high-resolution stereotactic imaging.<\/p>\n\n\n\n

To assure quality of patient care the procedure involves a multidisciplinary team consisting of a neurosurgeon, radiation oncologist and medical physicist.<\/p>\n\n\n\n

Stereotactic radiosurgery typically is performed in a single session, using a rigidly attached stereotactic guiding device, other immobilization technology and\/or a stereotactic image-guidance system, but can be performed in a limited number of sessions, up to a maximum of five. Technologies that are used to perform SRS include linear accelerators, particle beam accelerators and multi-source Cobalt 60 units. In order to enhance precision, various devices may incorporate robotics and real time imaging.<\/p>\n\n\n\n
