Existence and Uniqueness for Electrode Models for Electric Current Computed Tomography

摘要: The following experiment is considered. To a body of given conductivity, number electrodes are attached, through which current sent. On the same electrodes, resulting voltages measured. This can be described by mathematical models [K.-S. Cheng et al., IEEE Transactions on Biomedical Engineering, 36 (1989), pp. 918–924]. These discussed and their predictions compared with experiment. In particular, model exhibited that capable predicting experimentally measured to within 0.1 percent. For this model, existence uniqueness associated electrical potential proved.
