Abstract:
1. A soft-field tomography system comprising: a plurality of transducers configured for positioning proximate a surface of an object and spaced apart along the object, at least one of the transducers being formed from at least one conductive ring that extends around the object, the at least one conductive ring including a discontinuity that defines a non-conductive portion, wherein the at least one conductive ring includes a continuous portion that extends around at least one-half of a circumference of the object; one or more excitation drivers coupled to the plurality of transducers and configured to generate excitation signals for the plurality of transducers; 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; and a soft-field reconstruction module configured to reconstruct a property distribution based on the excitation signals and the measured response.
