    摘要： Transducer configurations and methods for transducer positioning in electrical impedance tomography are provided. A plurality of transducers for one electrical impedance tomography arrangement are configured for positioning proximate a surface of an object and spaced apart along the object, wherein the transducers are one or more conductive rings and have at least one non-conductive portion. The arrangement further includes one or more excitation drivers coupled to the plurality of transducers and configured to generate excitation signals for the plurality of transducers. The arrangement also includes one or more response detectors coupled to the plurality of transducers and configured to measure a response of the object at the plurality of transducers to the excitation applied by the plurality of transducers based on the excitation signals. The arrangement additionally includes a soft-field reconstruction module configured to reconstruct a property distribution based on the excitation signals and the measured response.

    摘要： A method for determining characteristics of a multi-material object is provided. The method includes producing a rotating electric field by providing an applied electrical signal set of individual electrical signal patterns to electrodes surrounding the multi-material object. The method also includes obtaining a measured electrical signal of electrical signals from the electrodes corresponding to each electrical signal pattern applied. An electrical network is determined based on the applied electrical signal set, the measured electrical signal set and an inverse of the applied electrical signal set. The method further includes determining the characteristics of the multi-material object by analyzing the electrical network.

    摘要： A method for determining characteristics of a multi-material object is provided. The method includes determining an electric element matrix representing the multi-material object. The electric element matrix is pre-multiplied by a first mathematical transformation matrix to obtain a first transformed electric element matrix. The first transformed electric element matrix is post-multiplied with a second mathematical transformation matrix to obtain a second transformed electric element matrix. The method further includes determining the characteristics of the multi-material object based on the second transformed electric element matrix.
