An agar phantom possessing a cavity, which simulated the rectum, was employed in the experiment to evaluate temperature distribution at RF-heating. In the phantom, the rising temperature around the cavity at 0 and 6 o'clock, where the prostate is situated, was rather low. The temperature, however, rose prominently when the cavity was filled up with a condom containing 5 % NaCl solution. This suggested that NaCl solution facilitated the heating current around the cavity. These observations are thought to be applicable in cases of other malignancies in cavity organs such as the esophagus and bronchus, as well as prostatic cancer.
