| Popis: | A re-entrant type resonant cavity applicator for brain tumor hyperthermia treatment is presented. In this method, a human head is placed between the gap of the inner re-entrant cylinders, and is heated with electromagnetic fields stimulated in the cavity without contact between the surface of the human head and the applicator. First, the comparison of the computer simulation and experimental results were presented. The estimated temperature agrees with the measured temperature with an error of 10% or better. Second, a method to control the heating pattern was presented. In the method, a human head was moved towards the electrode. The controllable range of heating pattern was about 70% of the distance from the center of the agar phantom in the direction of depth. |
