Methods and systems for high fidelity electrical tomographic processes

A method for performing tomography via recovery of a distribution of an electrical property comprising the steps of:

• providing a target object or portion thereof to be imaged;
• providing a plurality of sensing electrodes with a nominally known geometric configuration;
• geometrically configuring the target object and the electrodes to place the target within a region effectively sensed by the electrodes;
• for each of a plurality of distinct fluid configurations, (i) configuring a void space between the target and the plurality of electrodes with a fluid configuration to beneficially alter a sensitivity map between the electrodes;
• (ii) making electrical measurements between pairs of the electrodes;
• and (iii) mathematically inverting the electrical measurements to recover a reconstruction of the electrical property within a volume using a computational device configured to receive the measurements.

A system for performing tomography via recovery of a distribution of an electrical property comprising:

• a plurality of sensing electrodes with a nominally known geometric configuration;
• a measuring circuit for making electrical measurements between the electrodes;
• a fluid configuration to beneficially alter a sensitivity map between the electrodes, in view of a nominal target material, or both a nominal target material and nominal target geometry;
• and
• a computational system configured to receive the electrical measurements and invert the measurements to recover the distribution of the electrical property within a volume.
