Abstract

The wide variatiation in the specific resistance of human tissues suggests that images of this property should show good contrast. However the relationship between the measurements of voltage which can be made on the surface of a conducting object and the resitivity distribution within the object is non-linear. This means that complete reconstruction of the resitivity distribution from such measurements in general requires the solution of a set of non-linear equations, but useful results have been obtained from linear approximations to the full solution.
