Abstract :
A phantom was designed for studying in vitro acquisition procedures and reconstruction algorithms for multifrequency electrical impedance tomography (EIT). The phantom mimics a circular region discretized in 208 square pixels whose sides are composed of Cole models. A modular design, based on plug-in boards, provides facilities for modifying the electrical parameters of any pixel. This phantom is used especially for studying tissue characterization by imaging the characteristic frequency
