The study tested coaxial needle electrodes to select the optimal design of the electrode system. We developed models of inhomogeneous media simulating a blood vessel and surrounding soft tissues, as well as models of coaxial needle electrodes. Moreover, we did an experiment to evaluate the influence of the geometric parameters of needle electrodes on their characteristics. Finally, we carried out a model study of needle electrodes in various versions for the evaluation of their characteristics.
