Stereotactic Systems, Frame-Guided, Radiosurgical
Definition : Frame-guided computer-aided stereotactic surgical systems designed to aid in the performance of radiosurgical procedures from the exterior of the body using a single high dose of ionizing radiation. These systems typically combine medical imaging, a rigid frame (e.g., a headframe) attached to the patient body for guidance, dedicated computer software, and a strong source of radiation. Frame-guided stereotactic systems typically provide medical images that show the location of the instruments relative to pre-operative images obtained from one or more imaging modalities such as computed tomography (CT) and/or magnetic resonance imaging (MRI). Dedicated systems using either gamma radiation (e.g., Cobalt 60 sources) or linear accelerators intended for particular applications such as intracranial and spinal neurosurgery are available.
