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.

Transducer configurations and methods for transducer positioning in electrical impedance tomography

An electrode array, a system and a method for reconstructing the distribution of electrical properties within a multi-material object. One embodiment includes electrodes arranged along a three-dimensional helical path to provide one or more helical arrays and circuitry to measure signals for calculating a conductivity or admittivity distribution representative of the interior of the structure. Image data may be obtained which is representative of the multi-material region.
