Image Guided Surgical Navigation
Image-guided systems are essentially like GPS (global positioning satellite)
systems for the anatomy of your head. These systems are used to aid the
surgeon in the confirming the location of critical structures when the
interior of the nose and sinuses is distorted by unusual anatomy or prior surgery.
To use the image-guidance navigation system, a CT scan of the sinuses,
is performed using a specific navigation system protocol. For some systems,
a special mask or markers are placed on your face during the scan to serve
as reference points. The CT scan is transferred to a disk, which is then
loaded into the image-guidance computer.
During surgery, a detection array or a mask is placed on the patient’s
head. The CT scan images loaded into the system are then calibrated to
the patient’s anatomy using set pre-set reference points, which
may be the mask or markers or specific anatomic points on the face. The
position of the sinus surgery instruments can then be tracked by the computer
by integrating the information detected from the patient’s pre-set
reference points and comparing it to the information on the CT scan map.
Designed for sinus surgery and advanced ENT applications, GE’s surgical
navigation system will enhance your confidence and ability to perform
more thorough and challenging procedures. Providing 3-Dimensional visualization
enables you to locate and avoid critical structures, such as the optic
nerve and brain, while safely navigating your way to the diseased area.
