Fiber-optic pressure transducer for use near MR magnetic fields.
Measurement of physiologic pressures in the vicinity of magnetic fields has been difficult because present pressure transducers contain conductive elements. A fiber-optic pressure transducer was developed that contains no conductive parts and is useful for making continuous pressure measurements within magnetic resonance magnetic fields.
