摘要： A temperature monitoring system for a medical device comprises an optical transmit/receive unit, an elongate optical fiber having a proximal end, a distal end, and an inner core extending between the proximal end and the distal end, and one or more fiber Bragg grating elements formed in the inner core of the optical fiber. The optical fiber is operably coupled to the transmit/receive unit at the proximal end. At least a portion of the optical fiber is also operably coupled to a medical device and is structured to measure temperature at one or more temperature sensing locations on the medical device.

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.

摘要： An active tracking system that overcomes the heating problems of conventional transmission line and signal line conductors is provided. The active tracking system includes at least one active tracking coil; at least one integrated circuit proximate the active tracking coil; a tracking receiver; a first MR safe means configured for transmitting a received signal to the tracking receiver; and a second MR safe means configured for communicating one or more signals from the tracking receiver to the integrated circuit at coil. The integrated circuit may also include frequency estimations, analog to digital conversion at the tracking coil location to reduce the amount of processing required in the tracking receiver thereby decreasing the potential for signals passing from the tracking coil location to the tracking receiver to interfere with MR imaging signals.
