Abstract

Imaging using Electrical Impedance Tomography requires repeated solution of the diffu- sion equation V • ( for successive approximations of the spatially varying conductivity, a. The dual reciprocity boundary element method is an attractive method for the efficient solution of the problem, and the feasibility of using such a method was shown earlier by us. In this article we attempt to optimize the method on an example problem by studying the influence of using different interpolating radial basis functions, and of the distribution of internal points on the accuracy of the solution. 1 Introduction In electrical impedance tomography (EIT) the distribution of impedances inside a volume is sought by apply
