Infrared is a type of light that we cannot see with our eyes. Our eyes can only see what we call visible light. Infrared cameras scan detect and provide visual representation of infrared energy emitted by objects. In navigated surgery, an infrared camera picks up the location and motion of special reflective spheres attached to human anatomy and physician instruments.
Occurring, carried out, or encountered during the course of surgery.
