Abstract
Methods and systems for high fidelity electrical tomographic processes are provided for herein. Specifically, the use of a purpose-selected fluid configuration is described, used to fill the void space between mechanically fixed sensing electrodes and the target object to sense and reconstruct. In some embodiments, this fluid configuration enhances or masks changes in electrical measurements in response to certain materials known or suspected to exist within the sensed volume. In other embodiments, a plurality of fluid configurations may be employed to improve the quality of reconstruction, or resolve additional spatial dimensions. Exemplary applications in medicine and manufacturing are also provided.
