Boundary element numerical method for electric field intensity generated by oblique twelve -needle electrodes in biological tissue

摘要

According to the electric field intensity of oblique twelve -needle electrodes (OTNE) in biological tissue, the discrete equations based on the mdetermination linear current density were established by the boundary element integral equations (BEIE). The non-uniform distribution of the current flowing from twelve -needle electrodes to conductive biological tissues was imaged by solving a set of linear equations. Then, the electric field intensity generated by OTNE in biological tissues at any point can be determined through the boundary element method (BEM). It means that this method has an important referenced significance for computing the electric field intensity generated by OTNE in bio-tissue.
