| Summary: | Title screen This paper presents a cheap and compact system designed to study the impedance properties of the examined objects. This system can be used in medicine to carry out imaging of biological tissue during the cold for operations. One of the main problems of cold application in medicine is the difficulty in determining the boundaries and depth of the cryogenic effect. This problem arises due to the individual characteristics of the tissue, different cooling rates and high temperature gradients during freezing. In order to increase the accuracy in determining the boundaries and depth of the cryogenic effect, the impedance properties of liquid and muscle tissue have been studied. Based on the data obtained from the developed system for the study of impedance properties, based on the AD5933 impedance meter, the obtained data were analyzed at temperatures ranging from minus 18 to plus 25 degrees Celsius in the frequency range from 1 to 100 kHz. |
