Title:  Lorentz force impedance tomography in 2D: theory and experiments

Abstract:   Lorentz force impedance tomography, also known as the Magneto-Acousto-Electric Tomography (MAET), is a novel hybrid modality that represents a stable, high-resolution alternative to the Electrical Impedance Tomography (EIT). As EIT, MAET aims at imaging of the non-uniform conductivity inside an object. To this end, the object is placed in a magnetic field and subjected to ultrasound waves. As a result, Lorentz force generates currents that can be measured outside of the object. After a short theoretical introduction into MAET, I will present the design of a simplified 2D MAET scanner we have built, and will discuss new mathematical problems associated with this device, and the methods that can be used to solve them. This is joint work with R.S. Witte and C.P. Ingram.
