Novel optical techniques are now being integrated into RF catheters in order to detect the changes in tissue properties. Loss of birefringence due to fiber denaturation at around 70ºC is related to changes in accumulated phase retardation and can be measured by polarization-sensitive optical coherence reflectometry (PS-OCR). Since irreversible thermal lesions are produced when the tissue reaches 50ºC, our goal was to seek the mathematical relationship between both isotherms.application/pdfengThis is the peer reviewed version of the following article: González-Suárez A, Herranz D, Berjano E, Rubio-Guivernau JL, Margallo-Balbás E.
