摘要：
Electrical impedance tomograph-v (EIT) is a developing imaging modality; for early detection of breast cancer. In an EIT system, a low-frequency, current is applied sequentially between different electrode pairs while voltage measurements are made at other electrodes to arrive at the electrical impedance values. The set of impedance measurement data is then computed to produce a 3D electrical conductivity map of the volume to be imaged. In this work,, the design, measurements, and inversion of a full 3D EIT system are discussed. Experimentally determined EIT images of phantom objects are presented. (c) 2008 Wiley Periodicals, Inc.
