Abstract

This paper describes the heating properties of a resonant cavity applicator for agar phantom with cooling effect of blood perfusion. The purpose of this study is to demonstrate the cooling effect around blood vessel. In our heating experiments, an agar phantom is placed between two inner electrodes and is heated by electromagnetic fields stimulated in the cavity. In the agar phantom, one tube was placed as blood vessel. Water circulates through the tube. We showed temperature distributions of the agar phantom heated by the re-entrant type resonant cavity applicator From these results, it was found that the cooling effects of blood perfusion appear at the heated area approximately 2 cm away from the tube.
