摘要：
An improved computationally efficient means of determining the capacitance matrix from the finite element representation of a capacitance tomography system is shown. This direct method is also applied to the analysis of impedance tomography for systems in which there exists either an insulating boundary or a conducting boundary. The paper discusses aspects of the direct solution method which can influence the solution time and accuracy, and the application of multi-frontal solution techniques, to enhance solution times on scalable parallel computing hardware.
