Stereotactic Systems

Definition : Systems based on three-dimensional (3-D) arrangements and techniques that are designed to aid in the performance of minimally invasive procedures by combining medical imaging, dedicated computer software, and instrument tracking systems for guidance. The systems provide the operator with real-time, three-dimensional positioning and orientation of probes and instruments relative to the patient's anatomy. Stereotactic systems may be based on real-time images shown in a video display (image-guided); guided by the position of devices relative to a rigid frame (i.e., frame-guided); or they may not use any image as a guide (imageless) during the procedure. Dedicated image-guided, frame-guided, and imageless stereotactic systems intended for surgical, radiosurgical, biopsy, and/or other invasive procedures are available.
