IGS systems are designed for use in sinus, spine, cranial, and skull base surgery. An IGS system combines a high-speed computer system and specialized software and tracking technology. Actual movements of surgical instruments are correlated to the patient’s preoperative medical images such as CT (computed tomography) or MRI (magnetic resonance imaging) and displayed on this computerized system’s display monitor.
IGS systems allow the surgeon to view 3-D images of the patient’s anatomy in response to the mouse or the tracked surgical instrument and manipulate the 3-D view in real time during the surgery. It is intended as an adjunct to the surgeon for precisely locating anatomical structures anywhere on the human body during either open or percutaneous procedures. It is indicated for any medical condition that may benefit from the use of stereotactic surgery and which provides a reference to rigid anatomical structures such as sinus, skull, long bone, or vertebra, visible on medical images such as CT, MRI, or X-ray.
The GE Medical Systems Navigation and Visualization Multiple Dataset Navigation option on the InstaTrak™ system is substantially equivalent to the Image Composer application on the Vectorvision iPlan™, manufactured by BrainLAB, and the StealthStation™ with StealthMerge application manufactured by Medtronic. Each of these devices also offers the capability to fuse multiple data sets from different imaging modalities. The GE Medical Systems Multiple Dataset Navigation application with InstaTrak™ has the same intended use and utilizes images from the same modalities as these devices.
