It is important to note that LA is performed in Magnetic Resonance (MR) environment, with optical fibers guiding the laser beams. As mentioned in our previous RFA blog, there are image-based temperature sensors like Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) as well, but they are very expensive and equipment compatibility is a serious limitation. Currently, the Fiber optic sensors (FOS) are widely used because of the MRI compatible instrumentation. There are many technologies in FOS, currently Fluoroptic and Fiber Bragg Grating (FBG) have been used, however there is significant measurement error that is caused by length of the fiber optic probe itself.
