Abstract
To evaluate the heating distribution, human body phantom which is equal to electrical characteristics of human tissue is important. In this paper, in order to facilitate insertion of the probe in the phantom, a prototype gel phantom (waist part) is investigated. Thermal characteristics and conductivity of gel phantom in the cylindrical acrylics case were evaluated. As a result, conductivity of the phantom is 0.613 S/m, which is equal to the conductivity of the human muscle at 8 MHz. Therefore it becomes equal to a theoretical value. Temperature rise at center between the electrodes was 5.6℃. These results are in good agreement with theoretically value.
