Preventing lead-tip heating and unintended stimulation during full-body MRI diagnostics.
MRI radiofrequency fields induce standing waves along implanted stimulation leads. In-line series ceramic inductors and co-axial filtering attenuate RF currents, keeping tip heating below 1.5°C.
Using non-ferromagnetic titanium Grade 5 and platinum-iridium alloys prevents mechanical deflection or displacement under 3.0 Tesla static magnetic fields.
