A receive coil ( 46, 46', 46 '') receiving a magnetic resonance signal includes an optical resonant cavity ( 82, 82', 82 '') having an electro-optically active medium (90, 90', 90''). A radio frequency antenna ( 80, 80', 80 '') is coupled with the electro-optically active medium such that reception of the magnetic resonance signal by the radio frequency antenna modulates an optical characteristic of the optical resonant cavity. An interventional instrument ( 48 ) is adapted for partial insertion into an associated imaging subject ( 16 ). The radio frequency antenna and the optical resonant cavity are disposed on a portion of the interventional instrument that is inserted into the associated imaging subject. At least one optical fiber ( 52, 54 ) is optically coupled with the optical resonant cavity. An end of the at least one optical fiber extends outside of the associated imaging subject when the interventional instrument is partially inserted.
