Application boundary element approach to compute the electric field intensity of the oblique four-needle electrodes

摘要

According to the electric field intensity of oblique four-needle electrodes (OFNE) in biological tissue, the discrete equations based on the indetermination linear current density were established by the boundary element integral equations (BEIE). The non-uniform distribution of the current flowing from four-needle electrodes to conductive biological tissues was imaged by solving a set of linear equations. Then, the electric field intensity generated by OFNE 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 OFNE in bio-tissue.
