OBJECTIVE A study is carried out of the spatial distribution and time dependence of electric and thermal fields in the tissue around a radiofrequency (RF) electrode used in pain therapy. Finite-element calculation of the fields is performed, and results are compared with ex vivo tissue data. Field predictions are made for continuous and for pulsed RF applications. DESIGN A special RF cannula electrode is constructed with both macro and micro thermocouple sensors to measure both average and… CONTINUE READING
