Electromagnetic and thermal models of emission of a cooled directional for local endocavity hyperthermia

Possibilities of creation of controlled temperature fields in deep-seated biological tissue with the use of a microwave endocavity applicator with directed emission and surface cooling are explored. Mathematical models are proposed and calculated that make it possible to construct electromagnetic and thermal fields in biotissue depending on the specific thermophysical and ultrasound characteristics of the medium being irradiated, and to reveal situations and effects which should be achieved to solve problems of practical medicine in the field of local microwave hyperthermia of tissues.
