Optical Tracking

General Information
Curve is a wireless, touchscreen-operated planning and navigation system designed for pre- and
intraoperative use.
Optical tracking is achieved by a camera unit that emits and detects flashes of infrared light.
• Reflective elements, affixed to reference arrays on the patient and to instrumentation, reflect
the infrared signals back to the camera unit.
• Reflected signals from the reflective marker spheres and discs are captured and digitized by
each camera lens from a different angle.
• The software uses the camera input to calculate the relative three-dimensional positions of the
instruments and the patient reference arrays.
