Method and apparatus for eddy current compensation in a radio frequency probe

Systems and methods are provided for determining a characteristic of an associated in vivo sensor within a living body. A transmit coil produces an excitation signal, having a first orientation, to excite the in vivo sensor to produce a response signal. A receive coil produces a current in response to the response signal. The receive coil is oriented to interact with signals having a second orientation that is substantially orthogonal to first orientation. The probe further comprises at least one eddy current compensation coil that produces a compensation field. A component of the compensation field along the second orientation has a magnitude at the receive coil substantially equal and opposite to a magnitude of a similarly oriented component of a magnetic field associated with eddy currents induced within the body.
