Abstract :
Initial development and test of instruments for measuring anisotropic conductivity in vivo is difficult to carry out in animal models and would benefit from trials in a nonbiological physical model, a phantom. Here, a phantom that conducts heat anisotropically is described. The phantom also mimics the small-scale temperature nonuniformities that may be found near individual blood vessels. Design criteria, along with modeled and experimental results, are presented. Based on the analysis and experimental results, the time-dependence of the conductivity observed in living tissue is explained
