Imagine a GPS for surgery – guiding instruments with sub-millimeter precision without requiring a direct line of sight. That's the power of electromagnetic surgical navigation.
HISTORY / ORIGIN
Electromagnetic surgical navigation systems provide real-time navigation and guidance during surgical procedures, improving accuracy and reducing risks. Unlike optical tracking systems, electromagnetic systems do not require a line of sight.
TYPES OF ELECTROMAGNETIC NAVIGATION SYSTEMS
Electromagnetic navigation systems can be categorized by their tracking technology:
Electromagnetic Tracking Systems (EMTS) – Use electromagnetic radiation to locate the sensor or probe within the electromagnetic field.
Optical Tracking Systems (OTS) – The other major tracking technology.
Hybrid Navigation Systems – Combine electromagnetic and other tracking technologies.
Fluxgate Sensors – One type of electromagnetic sensor.
Wireless Sensors – Emerging sensor technology.
MATERIALS / KEY FEATURES
Electromagnetic navigation systems have several key features:
No Line of Sight Required – Can track instruments even when they are obscured.
Real-Time Tracking – Provides continuous, real-time navigation.
High Precision – Offers the precision of optical tracking.
Sensor Technology – Wired induction sensors are most widely adopted.
Improved Accuracy – Reduces surgical risks.
BENEFITS / WHY CHOOSE ELECTROMAGNETIC NAVIGATION
