Abstract
In order to utilize RF hyperthermia for the clinical cancer therapy, the development in dosimetry of the RF absorbed power in situ is considered to be necessary. In the present experiments, it was clarified that RF absorbed power distribution in agar-physiological salt solution phantom can be estimated from time variation of temperature which is measured by a fine thermocouple introduced to the phantom after heating process.
