BIOIMPEDANCE ANALYSIS IN THE DIAGNOSIS OF SKIN CONDITION

The number of visits and calls to doctors with dermatological diseases is growing rapidly every year and every year the number of cases with malignant skin tumors increases catastrophically. In medical practice, the diagnosis of any skin disease occurs by a doctor in several stages: history taking, visual examination with percussion and palpation, referral to the laboratory, if it is really necessary, for additional examination and diseases differentiation. The last stage is the most expensive due to the duration of the analysis process time, and with malignant neoplasms - this is a very critical factor because it affects the effectiveness of the further treatment and survival chance. In addition, without the conclusion of the laboratory and tests to provide recommendations for specialized treatment is almost impossible, because the doctor being in the dark and should act more at random, not at instructions with accurate information and diagnosis. Given this, there is a need for diagnostic tools that will allow dermatologists to quickly and by hand differentiate pathological conditions. The aim of this work is to find significant differences in the values of capacity and impedance of healthy tissues and tissues with cancers of varying severity, lesions, and dislocations. The founded differences can be used to predict and diagnose malignancies and cancer of the upper layers of the skin. Based on the results of experiments, an impedance analyzer of the state of biological tissue is proposed for use, the structural scheme and principle of operation of which is illustrated in the work. The results of this study can serve as a key factor and starting point in the future expansion of the tools of dermatological offices, in order to improve the efficiency of rapid diagnosis and identification of dermatological diseases, without waiting for the results of histological examinations.
