Acousto-electrical speckle pattern in Electrical Impedance Tomography

Lorentz Force Electrical Impedance Tomography (LFEIT) is a medical imaging technique of the tissue electrical impedance. It is based on the transmission of an ultrasound beam in a medium placed in a magnetic field, which induces an electrical current due to Lorentz force. The measurement of this current with electrodes allows to produce electrical impedance images with a spatial resolution close to ultrasound (US) imaging. The goal of this study is to assess the existence of an “acousto-electric speckle” in the LFEIT technique, by similarity to the US speckle.
