Dielectric Properties of Solid Tumors During Nonnothermia and Hyperthermia

Dielectric properties of five rat mammary carcinomas, one rat glioma, and rat muscle were measured in vitro at 37 and 43 °C over a frequency range of 1 MHz-1 GHz. No significant differences were observed in the measured dielectric properties of normal and neoplastic tissues, presumably due to the high water content of both types of tissues.
