Clinical investigations have suggested that absorption of radiofrequent energy may differ between normal tissue and endometrial carcinoma. Such an effect can be caused by certain biological properties of the tissue, influencing the function of the electronic circuit which contains the RF emitting coil. The changes of the circuit have to be extracted via electronic devices and translated into information of diagnostic significance. Three different types of detector circuits, the resonance circuit, the marginal oscillator and four bridge circuits have been studied. The fundamental resonance circuit has been found to represent the most reliable device for the extraction of information of medical importance. The data presented in this paper is part of a more extensive investigation, with the ultimate aim to evaluate the depth of penetration of endometrial carcinoma into the myometrium. Such evaluation will facilitate individualized treatment of corpus carcinoma.
