1. A method of determining the external shape of a body comprising placing a plurality of surface electrodes at spaced intervals around the body, causing currents of known value to flow in the body by applying an electrical current between pairs of electrodes in sequence, in each case measuring potentials between other pairs of electrodes, using the measured potentials to calculate estimated distances between the corresponding points of current introduction and of potential measurement, and determining estimated electrode positions consistent with these distances, which estimated electrode positions define the external shape of the body.
