Surgical navigation systems are advanced technologies used during operations to enhance precision and safety. They provide real-time guidance to surgeons by integrating imaging data, such as CT scans or MRI, with the surgical field. This allows for accurate localization of anatomical structures, helping to avoid critical areas and improve outcomes. These systems often use optical tracking or electromagnetic tracking to monitor the position of surgical instruments. By displaying this information on a screen, surgeons can make informed decisions and adjust their techniques as needed. Overall, surgical navigation systems play a crucial role in complex procedures, such as neurosurgery and orthopedic surgery.
