ELECTROMAGNETIC NAVIGATION
| Optical tracking that uses a camera to "flood" the surgical field with infrared light is the most typical method used in computer-assisted orthopaedic procedures. However, Zimmer and Medtronic -- Partners in CAS Technology -- are setting new standards with devices that employ electromagnetic (EM) tracking. |

EM systems use a magnetic field to detect and track miniature Patient
Trackers and instruments in space. The orientation and movement of the
Tracker are measured in real time to show the relative positions of
anatomy and instruments. View EM Brochure |
