抄録

This paper described basic study of a resonant cavity applicator with a monitoring system using an ultrasound imaging system. In our previous study, we reconstructed a 3-D model from a 2-D ultrasound images to detect the location and size of the target and to calculate temperature distributions inside the 3-D model. From the results of computer simulations, we estimated the suitable condition for heating target efficiently. In the present paper, first, we performed heating experiments of the agar phantom using the suitable condition for heating target efficiently. Second, a comparison of the estimated temperature and estimated temperature was presented. From these result, we found that the proposed system is useful for effective hyperthermia treatments.
