A system of electrodes for a bioimpedance spectrometry device has been developed. This device measures the resistance of biological tissues for given frequencies of electric current. The device is able to assess the state of organs and tissues of biological structures in case of breast cancer, as well as under various external influences. It differs from all existing bioimpedance spectrometry devices in that it has small dimensions, is capable of changing the frequencies of the probing current and at the same time immediately fixing the impedance values, and the system of electrodes has a hemispherical shape, and to obtain more accurate impedance data, each electrode is equipped with a spring that is attached to a dielectric hemisphere. The aim of the study is to study breast cancer using the developed system of electrodes for a bioimpedance spectrometry device. Patients with breast cancers were studied using a bioimpedance spectrometry device. The study of the impedance data obtained from the subjects with the presence of cancer in the breast and breast without deviations showed that the impedance of the breast affected by cancer lies in the range of 13...20 Ohm, depending on the frequency of the current. That is, the electrical resistance of the patient's affected chest is reduced to 13.6 %. The analysis showed that the diagnostics of cancer diseases can be carried out by the developed device for bioimpedance spectrometry. |
