| Outline of Final Research Achievements |
Microwave thermal therapy of cancers requires an efficient interstitial antenna which destroys spherical cancer of early stage and a margin of healthy tissues while minimizing damage to the rest of the organ. In this study, we design a new coaxial-slot antenna for liver or breast cancers. The needle tip consists of ceramic sandwiched between conductors to suppress a heat transfer. The heating characteristics agree well with those of the phantom experiments. We also propose an embedded choke type coaxial-slot antenna which improved the antenna mentioned above. Numerical results show that the antenna heats only the cancer selectively.
