Abstract
A planar sensor array for use in a surgical navigation system comprising at least one substrate and at two layers of a plurality of planar sensor coils formed on or within the at least one insulating substrate. The planar sensor array may be an electromagnetic planar transmitter coil array or an electromagnetic planar receiver coil array that includes at two layers of a plurality of planar electromagnetic transmitter or receiver spiral-shaped coils formed on or within the at least one substrate. The surgical navigation system includes the use of at least one magnetoresistance reference sensor attached to a fixed object; at least one magnetoresistance sensor attached to an object being tracked; and a planar sensor coil array communicating with the at least one magnetoresistance reference sensor and the at least one magnetoresistance sensor to determine the position and orientation of the object being tracked.
