This study elucidates development of new interstitial RF heating methods, combining with external RF heating using paired electrodes, heating the subject broadly in advance in order to selectively extend the heating region. Two kinds of heating system were developed by controlling a differential mode and a common mode of RF currents. Heating experiments with a liquid adhesive subject enabled a wider effective heating region with higher initial temperatures of heating subjects by external RF heating, and larger interstitial electrode diameter., 針状挿入電極だけを用いた内部加温法では, 被加温部位を限定できるが加温領域が狭いという問題があった.本論文では, 選択的に加温できる内部RF加温法に, 対極板を用いた外部RF加温法を組み合わせて, あらかじめ生体全体を加温することにより, 加温領域を拡大する方法を開発した.ディファレンシャルモードとコモンモードのRF電流を制御する加温システムを構築した.2種類の方法を工夫した.アドヘア糊を用いた加温実験の結果, 外部RF加温による被加温体の初期温度が高いほど, また円筒型電極の直径が大きいほど, 加温領域を効率的に拡大できることを示した.}, pages = {231--244}, title = {Fundamental Study of a Combined Hyperthermia System with RF Capacitive Heating and Interstitial Heating}, volume = {17}, year = {2001} }
