Electrical Impedance Tomography with Interior Measurements
Abstract: The classical problem of Electrical Impedance Tomography is to image the resistivity of a tissue from boundary measurements of currents and voltage. In 1992, M. Joy, an engineer at Uof Toronto, demonstrated that (direct/low frequency) current density can be traced inside the body by using Magnetic Resonance Imaging. This discovery opened a class of new problems in EIT with interior information. Initiated independently by A. Nachman (Canada) and Kim Seo (Korea) such problems pose serious mathematical challenges. I will outline some of them and briefly describe my recent work on it.
