Abstract
A systematic methodology for the evaluation of the global performance of medical EIT systems has been developed. It consists of a saline phantom in which calibrated contrasting test objects are reproducibly positioned using a position controller and a set of evaluation parameters to characterize: i) data and image noise, ii) data accuracy, iii) detectability of single contrasts, iv) distinguishability of multiple contrasts, and v) accuracy of reconstructed image i.e. amplitude, resolution, position and shape. Using this approach, CSEM has evaluated three different EIT systems.
