Electrical impedance tomography (EIT) is a developing and promising imaging modality for early detection of breast cancer. An EIT system utilizes an array of electrodes to apply currents to an imaging domain and measures the resulting voltages on the periphery. The measurement results are then input to a reconstruction algorithm to produce an image of the impedance distribution inside the domain. In this work, a full 3D BIT system has been developed and the system design, measurement strategy and reconstruction algorithm are presented. Several sets of experimental data are collected and phantom tumor images are reconstructed from these data sets. © 2006 IEEE.
