摘要：

An impedance imaging system based on the use of induced currents is described. The principle of operation is discussed and a back projection process appropriate for induced currents is developed. Results from a two dimensional laboratory phantom which demonstrate the performance of the system are presented and some differences in behaviour between induced and injected current systems are identified.
