我们总结了各种犬肿瘤组织和正常组织的介电常数和电导率，以及从巨型藤壶中切除的单个肌肉纤维，频率从10 MHz到18 GHz，重点是组织介电特性的机制。我们讨论了介电性能随组织含水量的变化，并提供了简单的经验公式，以便在净组织含水量的基础上估计其他软组织的介电性能。从这些考虑出发，我们考虑活体组织与切除组织的介电特性的可能变化，以及肿瘤与正常组织的介电特性。
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 thai 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.
