number of wires that you have to contend with: the instrument used
to drive navigation, the navigation probes, the suction devices, the
light wand, the camera head. That's a lot of wires to move your fingers
around in such a confined space. The downside of RF is that you
must maintain a direct line of sight between the navigation system
and the navigation instruments. Space is another consideration with
RF systems. Some require the patient to be 4 or 5 feet away from the
system to orient the image of the patient within the geometry of the
operating room. If you don't have enough space in the OR, you can
run into trouble. OSM
