M. Ovchinnikov7, and N. A. Vetrova3 The physical basis of microwave radiometry and the construction and technical characteristics of different types of antenna applicators used in medical radiometers are discussed. We present results obtained during the devel opment and the potential uses of new types of antenna applicators in different areas of medicine. Introduction antenna. Integration is performed in terms of BO volume, V. W(r) is defined as The principle of action of microwave radiometers is based on recording microwave radiation from biological objects (BO) whose temperature is above absolute zero. (2) Measurements of the intensity of body radiation can be used to determine its temperature. This method is termed microwave radiometry (MR). MR is a functional diag nostic method based on passive radioheat location [1]. where P is the electromagnetic power loss density per unit In contrast to infrared thermography, MR provides for volume due to absorption, P0 is the total power dissipat noninvasive identification of thermal anomalies at depths ed, E(r) is the tension of the electric field of th
