Abstract
A method of, and apparatus for, real-time imaging are described employing a plurality of contact electrodes (1) located for example around the thorax (2) with simultaneous measurement of potential between adjacent pairs of electrodes (1), digital demodulation of the potentials, and measurement and division of the drive current into the potential measurements before image reconstruction by the use of transputers (20, 22, 24 and 26).
