A new method of monitoring
temperature non-invasively within an MRI scanner is introduced. This method is
based on Raman backscattering, with the sensor consisting of a long length of
thin optical fibre which can be arranged in any desired geometry. The major
advantage over existing techniques is that a wide area of surface temperatures
can be monitored simultaneously. Preliminary feasibility of the approach is
shown here for localized and global temperature measurements.
