Minimally invasive surgical procedures require advanced motion tracking technology that can locate surgical instruments and tools inside the human body when there is no clear line of sight. Electromagnetic tracking (EMT) technology enables this performance: Electromagnetic coils drive the “six degrees of freedom,” known as 6DOF, that empower surgeons and clinicians to clearly visualize and navigate the human body. Today, advancements in electromagnetics are increasing 6DOF accuracy without increasing the size of the device.
