Stereotactic Systems, Image-Guided, Radiosurgical
Definition : Image-guided computer-aided stereotactic surgical systems designed to aid in the performance of surgical procedures from the exterior of the body using a single high dose of ionizing radiation. These systems typically combine medical imaging, dedicated computer software, and a strong source of radiation. Image-guided radiosurgical systems work in a way similar to global positioning systems (GPS) applied to the human body. The systems provide surgeons with real-time, three-dimensional (3-D) positioning and orientation of the target and the radiation source relative to the patient's anatomy on a video display during the procedure. One or more imaging modalities, such as computed tomography (CT) and/or magnetic resonance imaging (MRI), may be used in the procedure. Dedicated systems that use linear accelerators and are intended for particular applications such as intracranial and spinal neurosurgery (e.g., brain, neck, and spinal tumors), orthopedic, and laryngological procedures, are available.
