摘要:
An MRI compatible electrode circuit construct is provided. The construct includes at least three filter components constructed from a continuous or non-continuous electrode wire. One filter component may be a resonant LC filter proximate an electrode/wire interface. A second filter component may be a resonant LC filter adjacent a proximal termination of the wire construct. The filters resolve the issue of insufficient attenuation by effectively blocking the RF induced current on the wire from exiting the wire through the electrode and at the terminal or proximal end. The third filter component may include one or more non-resonant filter(s) positioned along the length of the electrode wire that resolve(s) the issue of excessive heating of the resonant LC filters by significantly attenuating the current induced on the wire before it reaches the resonant LC filters.
