The article deals with the results of prehospital appraisal of hyperplasia of the mammary glands in 364 females by means of infrared thermovision techniques and UHF-radiothermometry. The thermovision and radiothermometric signs of this pathological condition are described. Examination conducted in the course of the disease twice in 52% and 3 to 4 times in 30% of cases showed radiothermometry to be highly informative in optimization of the management of patients with mastopathy. The feature of the thermal metabolic process in cancer was revealed. The proposed radiothermometric method may be used as an auxiliary criterion for appraising the condition of the mammary tissues.

The authors used a new noninvasive method, decimeter radiothermometry, to measure cerebrocranial temperature in 68 patients with brain tumors. It made it possible to study the mean temperature of a tissue layer situated at a depth of 3-5 cm from the surface to an accuracy of up to +/- 0.1 degrees C. Temperature anomaly at the site of the tumor projection was revealed in three fourths of cases, mainly when it was localized laterally. Cerebrocranial temperature was compared with the morphological structure of the tumor. The diagnostic value of the method in tumors of the brain is demonstrated.

The technique of absolute measurements of an internal human body temperature is proposed from the estimation of the intrinsic heat radiation over the radiofrequency range. Its principle is based on the thermodynamic equilibrium of the radiometer inputs. The method and the equipment are capable of providing measurements of the average depth temperature with the accuracy of +/- 0.1.
