Abstract

We summarize the dielectric permittivity and conductivity of various canine tumor and normal tissues, and single excised muscle fibers from the giant barnacle, at frequencies from 10 MHz to 18 GHz, with emphasis on the mechanisms that are responsible for the dielectric properties of the tissues. We discuss the variation in the dielectric properties with tissue water content and provide simple empirical formulas to allow the estimation of the dielectric properties of other soft tissues on the basis of the net tissue water content. From these considerations, we consider the possible variation in dielectric properties of living tissue in situ, with those of the excised tissue, and of tumor vs. normal tissues.
