This paper discusses temperature distributions of the improved re-entrant resonant cavity applicator with 3-D FEM abdominal model. We proposed a resonant cavity applicator with metal shields for preventing the edge effect on human abdominal regions. In this paper, first, we reconstructed a 3-D human abdominal model from ultrasonic images. Second, proposed heating method was described. Finally, from the results of specific absorption rate (SAR) distributions and temperature distributions using 3-D FEM, it was shown that the heated area inside a human abdomen could be controlled by changing the electromagnetic field distributions. From these results, it was found that the improved re-entrant resonant cavity applicator was useful for effective hyperthermia treatments.
