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.

MRI compatible medical device temperature monitoring system

A method of estimating temperature includes selecting a plurality of known calibration temperature values; determining a bulk wavelength for each of the calibration temperature values; formulating a calibration data set that includes the plurality of known temperature values and the corresponding plurality of bulk wavelengths; and using the calibration data set to determine an estimated current temperature value based upon a current bulk wavelength, wherein the current temperature value is estimated based upon one or more data points in the calibration data set.
