Abstract
An experimental system for impedance tomography has been constructed. The acquisition system uses 16 multifunctional active electrodes, each including a current source and a voltage buffer. Images of active and reactive parts of different target impedances in a phantom filled wit h liquid have been obtained. The system performance has been compared with those of other systems using either a mesh phantom or rods as poi nt sources used for the determination of the modulation transfer funct ion.
