Abstract
In electrical impedance tomography the boundary shape is often inaccurately known. If the boundary shape is wrong (in a three-dimensional problem) there will not generally be an isotropic conductivity which fits the current and voltage data. Both the conductivity and boundary shape can be determined by electrical data together with three spatial measurements. In two dimensions errors in boundary shape could be accounted for by a change in conductivity, but not if the length scale on the boundary is also known.
