摘要：
A set of specifications thought useful to advance the utility of electrical impedance tomography as a clinical imaging modality is proposed, together with an approach to image reconstruction designed to fulfil these specifications. Computer simulations are used to investigate the performance of this reconstruction approach on simple, known, impedance distributions and to develop the method to the stage of a complete reconstruction algorithm. The algorithm is then tested on data sets produced by measurements on a physical phantom, and on a set of measurements made on a volunteer human subject
