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.
