The Measurement of Permittivity and Temperature of Tissues
There is at present much interest in the use of microwave induced hyperthermia.1 For most applications it is desirable to measure the temperature of the phantom tissue or animal being irradiated without the thermometer interacting with the microwave field. It is also believed that successful microwave hyperthermia requires that the electrical properties of the tissue, ie the permittivity ϵ′ and conductivity σ be known. The purpose of this publication is to report ways in which such measurements may be made.
