Dr. Boris Rubinsky, Arnold and Barbara Silverman Distinguished Professor, Bioengineering; Professor, Mechanical Engineering at the University of California, Berkeley introduces us to his revolutionary technology of Electrical Impedance Tomography (EIT). EIT develops an image of the electrical impedance of the body from electrical measurements around the body by placing electrodes around organs and injecting current at certain locations while measuring potential at others. It is a noninvasive procedure that uses inexpensive hardware: the medical imaging system will use cell phone technology to enable doctors around the world.
