Title: Lorentz force impedance tomography in 2D: theory and experiments
Abstract: Lorentz force impedance tomography, also known as the MagnetoAcoustoElectric Tomography (MAET), is a novel hybrid modality that represents a stable, highresolution alternative to the Electrical Impedance Tomography (EIT). As EIT, MAET aims at imaging of the nonuniform 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.
