Stereotactic Systems, Frame-Guided
Definition : Stereotactic computer-aided surgical systems designed to aid in the performance of minimally invasive procedures by combining medical imaging, dedicated computer software, and a rigid frame (e.g., headframe, body frame) attached to the patient body for guidance. The systems provide three-dimensional (3-D) positioning and orientation of instruments of the patient's anatomy relative to the frame position during surgery without the use of an endoscope. 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 frame-guided stereotactic systems intended for particular procedures such as intracranial neurosurgery and other intracranial and spinal procedures are available as are frame-guided systems intended to facilitate radiosurgical procedures.
