Abstract:
A method for remotely imaging internal structures of biological tissue using the technique of electrical impedance tomography (EIT), comprising the steps of:electrically connecting at least two electrodes to said tissue; applying electrical input currents, voltages, or combinations thereof, of predetermined values to at least one of said electrodes; measuring the values of resulting output currents, voltages, or combinations thereof, at at least two of said electrodes; transmitting said values of said electrical input currents, voltages, or combinations thereof, and said values of said resulting output currents, voltages, or combinations thereof, to a remote computer through a communications network; calculating at said remote computer, utilizing a front tracking technique, an electrical impedance value at one or more points on said tissue by analyzing said values of said electrical input currents, voltages, or combinations thereof, and said values of said resulting output currents, voltages, or combinations thereof; and generating an image of internal structures of said tissue corresponding to said calculated impedance value or values.
