System and method for correcting fault conditions in soft-field tomography

摘要

A soft-field tomography system includes a plurality of transducers configured for positioning at a surface of an object. An excitation driver is configured to generate a precomputed default excitation pattern for the plurality of transducers. A processor stores the precomputed default excitation pattern and a corresponding predicted response for the precomputed excitation pattern. The processor further stores one or more precomputed fault excitation patterns and corresponding predicted response for the fault excitation patterns corresponding to one or more fault conditions of the plurality of transducers. A response measurement device is configured to measure a response at one or more of the transducers to determine if a fault condition exists. If a fault condition exists, the processor at least one of instructs the excitation driver to generate a precomputed fault excitation pattern or uses a predicted response that corresponds to the fault condition for a soft field tomography process.

1. A soft-field tomography system comprising:
a plurality of transducers configured for positioning at a surface of an object, wherein the plurality of transducers correspond to a plurality of channels; an excitation driver coupled to the plurality of channels and configured to generate a precomputed default excitation pattern for the plurality of transducers; a processor electrically coupled to the excitation driver, the processor storing the precomputed default excitation pattern and a corresponding predicted response for the precomputed default excitation pattern, the processor further storing at least one precomputed fault excitation pattern and corresponding predicted response for the precomputed fault excitation pattern corresponding to one or more fault conditions of the plurality of transducers; and a response measurement device configured to measure a response at one or more of the transducers to determine if a fault condition exists, wherein, if a fault condition exists, the processor performs at least one of instructs the excitation driver to generate at least one of the precomputed fault excitation pattern or uses the predicted response that corresponds to one or more fault conditions for a soft field tomography process.
