摘要：
The invention relates to the field of medicine and medical technology, and more particularly to a radio thermometer intended for non-invasively measuring the temperature of internal tissues of a biological subject. The present radio thermometer comprises, connected in series, an applicator antenna for contact with a biological subject, a switch, a circulator, which is mounted downstream of the switch, a receiving device comprising an amplifier with bandpass filters, an amplitude detector, a narrow-band low frequency amplifier and a synchronous detector, an integrator, a dc amplifier, and a reference voltage generator, which is connected to the switch and to the synchronous detector. Additionally, the radio thermometer comprises a Peltier element, which is connected to an output of the receiving device, a first and a second microwave load, which are mounted on the Peltier element and are in thermal contact therewith, and at least one temperature sensor, which is adapted to measure the temperature of the microwave loads, wherein the first microwave load is adapted for connection to the switch, the switch is adapted to connect either the applicator antenna or the first microwave load to a first arm of the circulator, a second arm of the circulator is connected to the receiving device, and a third arm of the circulator is connected to the second microwave load. The invention provides for a reduction in measurement error when measuring the internal temperature of a biological subject and an increase in the accuracy of a radio temperature measurement method in the detection of malignant tumours, as well as a reduction in the overall dimensions of the device, an increase in ease of use and a reduction in manufacturing costs.Linvention se rapporte au domaine de la médecine et des techniques médicales, et concerne notamment un radio-thermomètre permettant de mesurer de manière non invasive la température des tissus internes dun objet biologique.
