Intracavity antenna for multichannel radiothermograph

The development of an intracavitary multichannel diagnostic radiothermograph based on monolithic integrated circuits will allow creating a medical device that allows diagnosing diseases of internal organs of the human body. Purpose: to consider the option of constructing a diagnostic intracavity antenna with several measurement channels for a multichannel radiothermograph built on the basis of monolithic integrated circuits. A variant of constructing a multichannel radiothermograph for intracavity thermometry, implemented in the form of an intracavity antenna with five channels, a microwave switch and a microwave single-channel radiometer, is proposed. The intracavity antenna allows you to measure the temperature at five points of the biological cavity. The antennas are switched using a multi-channel switch integrated with the microwave radiometer. The conducted theoretical studies confirm the possibility of using multichannel microwave radiometry in medicine for intracavitary thermometry The basis for creating a model of a multichannel microwave radiothermograph based on monolithic integrated circuits for intracavitary examination is laid.
